. AUDIO OUTPUT
The MT1379 supports two-ch nnel nd six-ch nnel n log udio output. In system configur tion with six n log outputs,
the front left nd right ch nnels c n be configured to provide the stereo (2 ch nnel) outputs nd Dolby Surround, or the left nd
right front ch nnels for 5.1 ch nnel surround system.
The MT1379 lso provides digit l output in S/PDIF form t. The bo rd supports both optic l nd co xi l SPDIF outputs.
6. AUDIO DACS
The MT1379 supports sever l v ri tions of n I2S type bus, v rying the order of the d t bits (le ding or no le ding zero bit,
left or right lignment within fr me, nd MSB or LSB first) is possible using the MT1379 intern l configur tion registers. The
I2S form t uses four stereo d t lines nd three clock lines. The I2S d t nd clock lines c n be connected directly to one or
more udio DAC to gener te n log udio output.
The two-ch nnel DAC is n AKM AK4382A. The DACs support up to 192kHz s mpling r te.
The outputs of the DACs re differenti l, not single ended so buffering circuit is required. The buffer circuits use N tion l
LM833 op- mps to perform the low-p ss filtering nd the buffering.
7. VIDEO INTERFACE
7.1. VIDEO DISPLAY OUTPUT
The video output section controls the tr nsfer of video fr mes stored in memory to the intern l TV encoder of the MT1379. The
output section consists of progr mm ble CRT controller c p ble of oper ting either in M ster or Sl ve mode.
The video output section fe tures intern l line buffers which llow the outgoing lumin nce nd chromin nce d t to m tch
the intern l clock r tes with extern l pixel clock r tes, e sily f cilit ting YUV4: 2:2 to YUV4: 2:0 component nd s mple
conversion. A polyph se filter chieves rbitr ry horizont l decim tion nd interpol tion.
Video Bus
The video bus h s 8 YUV d t pins th t tr nsfer lumin nce nd chromin nce (YUV) pixels in CCIR601 pixel form t (4:2:2).
In this form t, there re h lf s m ny chromin nce (U or V) pixels per line s lumin nce (Y) pixels; there re s m ny
chromin nce lines s lumin nce.
Video Post-Processing
The MT1379 video post-processing circuitry provides support for the color conversion, sc ling, nd filtering functions through
combin tion of speci l h rdw re nd softw re. Horizont l up-s mpling nd filtering is done with progr mm ble, 7-t p
polyph se filter b nk for ccur te
non-integer interpol tions. Vertic l sc ling is chieved by repe ting nd dropping lines in ccord nce with the pplic ble
sc ling r tio.
Video Timing
The video bus c n be clocked either by double pixel clock nd clock qu lifier or by single pixel clock. The double clock typic lly
is used for TV displ ys, the single for computer displ ys.

10
8. FLASH MEMORY
The decoder bo rd supports 70ns Fl sh memories. Currently 4 configur tions re supported:
 FLASH_512K_8b
 FLASH_1024K_8b
 FLASH_512Kx2_8b
 FLASH_512Kx2_16b
The MT1379 permits both 8- nd 16-bit common memory I/O ccesses with remov ble stor ge c rd vi the host interf ce.
9. SERIAL EEPROM MEMORY
An I2C seri l EEPROM is used to store user configur tion (i.e. l ngu ge preferences, spe ker setup, etc.) nd softw re
configur tion.. Industry st nd rd EEPROM r nge in size from 1kbit to 256kbit nd sh re the s me IC footprint nd pinout. The
def ult device is 2kbit, 256kx 8, SOIC8 SGS Thomson ST24C02M1 or equiv lent.
10. AUDIO INTERFACE AUDIO SAMPLING RATE AND PLL COMPONENT CONFIGURATION
The MT1379 udio mode configur tion is select ble, llowing it to interf ce directly with low-cost udio DACs nd ADCs. The
udio port provides st nd rd I2S interf ce input nd output nd S/PDIF (IEC958) udio output. Stereo mode is in I2S form t
while six ch nnels Dolby Digit l (5.1 ch nnel) udio output c n be ch nneled through the S/PDIF. The S/PDIF interf ce consists
of bi-ph se m rk encoder, which h s low skew. The tr nsmit I2S interf ce supports the 112, 128, 192, 256, 384, nd 512
s mpling frequency form ts, where s mpling frequency Fs is usu lly 32 kHz, 44.1 kHz, 48 kHz, 96 kHz, or 192 kHz. The udio
s mples for the I2S tr nsmit interf ce c n be 16, 18, 20, 24, nd 32-bit s mples.
For Line r PCM udio stre m form t, the MT1379 supports 48 kHz nd 96 kHz. Dolby Digit l udio only supports 48 kHz. The
MT1379 incorpor tes built-in progr mm ble n log PLL in the device rchitecture in order to gener te m ster udio clock.
The MCLK pin is for the udio DAC clock nd c n either be n output from or n input to the MT1379. Audio d t out (TSD) nd
udio fr me sync (TWS) re clocked out of the MT1379 b sed on the udio tr nsmit bit clock (TBCK). Audio receive bit clock
(RBCK) is used to clock in udio d t in (RSD) nd udio receive fr me sync (RWS).
11. FRONT PANEL
11.1. VFD CONTROLLER
The VFD controller is NEC uPD16311. This controller is not processor, but does include simple st te m chine which
sc ns the VFD nd re ds the front p nel button m trix. The 16311 lso includes RAM so it c n store the current st te of ll
the VFD icons nd segments. Therefore, the 16311 need only be ccessed when the VFD st tus ch nges nd when the button
st tus is re d. The MT1379 c n control this chip directly using PIO pins or c n llow the front p nel PIC to control the VFD.

75R input nd output imped nce. This control volt ge llows devices to over-ride the composite video input with RGB inputs,
for ex mple when inserting closed c ption text. It is c lled f st bec use this c n be done t the s me speeds s other video
sign ls, which is why it requires the s me 75R imped nces.
0 to 0.4V: TV is driven by the composite video input sign l (pin 19). Left unconnected, it is pulled to 0V by its 75R
termin tion.
1V to 3V: the TV is driven by the sign ls Red, Green, Blue nd composite sync. The l tter is sent to the TV on pin 19.
This sign l is useful when using TV to displ y the RGB output of devices such s home computers with TV-
comp tible fr me r tes. Tying the sign l to 5V vi 100R forms potenti l divider with the 75R termin tion,
holding the sign l t round 2V. Altern tively, if TTL level (0 to 5V) neg tive sync pulse is v il ble, this will
be high during the displ y periods, so this c n drive the bl nking sign l vi suit ble resistor.
Control Voltage
0 to 2V = TV, Norm l.
5 to 8V = TV wide screen
9.5 to 12V = AV mode

13. CIRCUIT DESCRIPTION
13.1. POWER SUPPLY
 Socket PL1 is the 220VAC input.
 2.5A fuse F1 is used to protect the device g inst short circuit.
 Line filters nd c p citors L1, C1, L5 nd L6 re used to block the p r sitic coming from the m ins. They lso prevent the
noise, produced in the circuit, from being injected to the line.
 Volt ge is rectified by using diodes D1, D2, D3 nd D4. Using c p citor C3 (470mf) DC volt ge is produced. (310- 320VDC).
 The current in the prim ry side of the tr nsformer TR3 comes to the SMPS IC (IC3 TOP223Y). The SMPS IC h s three-pin
TO-220 c se nd cooler is mounted on it. It h s built-in oscill tor, overcurrent nd overvolt ge protection circuitry nd runs
t 100kHz. It st rts with the current from the prim ry side of the tr nsformer nd follows the current from the feedb ck winding.
 Volt ges on the second ry side re s follows: -22V, -12V, 3.3V, 5V, 15V.
 D14 TL431 is const nt current regul tor. TL431 w tches the 5 volts nd supplies the required current to IC2. There re
LED nd photo tr nsistor in IC2. The LED inside the IC2 tr nsmits the v lue of the current from D14 to phototr nsistor.
Depending on the current g in of the phototr nsistor IC3 keeps the volt ge on the 5-volt-winding const nt.
 Adjust ble volt ge regul tor IC5 (LM317) supplies 12 Volts.
 When the device enters st nd-by mode, tr nsistor Q2 st rts to conduct nd pulls the djust pin of IC5 to ground, where this
cuts 12Volts off.
 22 Volts is used to feed the VFD (V cuum Fluorescent Displ y) driver IC on the front p nel.
 Tr nsistor Q4 nd zener diode D14 re used to regul te +12 Volts. This volt ge is used to feed op- mps on the b ck p nel.
13.2. FRONT PANEL
 All the functions on the front p nel re controlled by U7 (MT1379) on the m inbo rd.
 U7 sends the comm nds to IC2 uPD16311 vi socket PL1 (pins 3,4 nd 5).
 There re 16 keys sc nning function, 2 LED outputs, 1 St nd-by output nd VFD drivers on IC2.
 Pin 52 is the oscill tor pin nd is connected vi R5 56K.
 LED D6 is red in st nd-by mode nd green when the device is on. When entering st nd-by mode, pin 48 goes HIGH (+5V)
nd controls the tr nsistor Q2 on the power bo rd.
 V cuum fluorescent displ y MD2 is speci lly designed for DVD.
 The sc nned keys re tr nsmitted vi IC2 pin 5 nd 6 to U1 on the m inbo rd.
 IR remote control receiver module IC3 (TSOP1836) sends the comm nds from the remote control directly to U1.
 Socket PL2 c rries the VFD fil ment volt ge nd 22 Volts.
13.3 BACK PANEL
 There re 1 SCART connector (PL4), 2 pieces RCA udio j cks, for udio output, 1 co xi l digit l udio output JK3 nd 1 l ser
digit l udio output PL5 on the b ck p nel.
 TOTX176 is used for l ser output.
 For co xi l udio output SPDIF is used.
 Q22 .. Q27 tr nsistors re to mute the udio outputs while switching the st te of the unit(power on/off)
 There re two op- mps in U14, U16 nd U18. They re used for left,right,re r left nd right, subwoofer center udio ch nnels.
The feedb ck resistor is mplifying the g in.
 SCART pin 8 controls 16:9 nd 4:3 mode using Q28,Q29 nd Q30.
 When the pin8 output of the sc rt becomes 5 Volts, 4:3 mode is selected nd 16:9 mode is selected when this output becomes
0. The circuit is djusted to output 12 Volts for 4:3 mode nd 6 Volts for 16:9 mode.
 Tr nsistors Q28,Q29 nd Q30 tr nsmit these volt ges when the device is turned on nd cuts them off when it is turned off.
 FBL on pin 16 tr nsmits 5 Volts vi tr nsistors Q12 nd Q14 when the device is on.
