Section 2
Circuit Description
2-1. BI-156 Board
The output signal (at pin 8 of IC101) from a CCD imager (IC101) is passed through a buffer (consisting
of Q102 and Q101) and output from pin 12 of IC101 to the PR-269 board. H1, H2, V1, V2, V3, and V4
pulses are a CCD drive pulse supplied from the PR-269 board.
2-2. PR-269 Board
2-2-1. Main Signal Processing Circuit
The CCD-OUT signal (at pin 12 of CN201) output from the BI-156 board is input to pin 30 of IC201 for
CDS (Correlative Double Sampling). Moreover, the CCD-OUT signal is amplified using an AGC circuit.
The 10-bit data (at pins 3 to 12 of IC201) of an A/D-converted A/D output signal is input to wide
dynamic signal processing DSP (pins 1, 2, and 5 to 12 of IC203). In DSP, an exposure signal is
simultaneously processed for a long or short time and output as 10-bit data (at pins 37 to 43, and 46 to 48
of IC203). The output signal is then input to DSP CORE signal processing circuit IC204 (pins 55 to 64 of
IC204). After the input signal is digital-processed in IC204, it is converted from digital to analog so as to
produce an analog Y/C output signal (Y signal at pin 12 of IC204 and C (chroma) signal at pin 13). The
Y/C output signal is passed through filters (FL202 for Y, FL201 for C), respectively. After that, the
signal is added and output through an amplifier (consisting of IC207 and IC296) from pins 15 and 16 of
CN203.
2-2-2. Microcomputer’s Peripheral Circuit
The parameters of a digital signal processing circuit (consisting of IC203 and IC204) are set using a
microcomputer (IC304). The parameters are partially stored in E2PROM (IC306). The analog data
control for the peripheral circuit is performed in the form in which the digital data from a microcomputer
is passed through a D/A converter (IC301).
2-2-3. CCD Drive Pulse Signal Circuit
The CCD drive pulse signal circuit generates a CCD horizontal/vertical drive pulse and sample & hold
pulse using TG (IC202) to which a main clock of 57 MHz is input. The sync signal sent to TG is
obtained from SG in IC204.

2-2 SSC-DC593/DC593P/DC598P (E)
2-2-4. External Sync Circuit
This camera is compatible with VS synchronization and MPX-VD synchronization (SSC-DC690) or LL
synchronization (SSC-DC593/593P/598P).
VS: The sync source VS signal from pin 13 of CN203 is clamped using IC205 and then input to
pin 34 of IC204 so as to constitute VReset/H-PLL. The H-phase comparison output signal at
pin 23 of IC204 is passed through a low-pass filter (LPF) around IC503 and reflected on
internal master LC-type VCO (around IC508). Synchronization is detected using IC204.
LL: The V pulse (power frequency sync pulse) from pin 13 of CN203 is input to pin 35 of IC204
and V-reset inside IC. The V pulse and an internal VD pulse constitute PLL. The V-phase
comparison output signal (at pin 23 of IC204) is passed through a low-pass filter around
IC503 and reflected on internal master LC-type VCO (around IC508).
MPX-VD: The sync source VD signal separated from the superimposition line in a DC-DC converter is
obtained from pin 13 of CN203. After the signal is waveform-shaped around IC210, it is
input to pin 35 of IC204 and V-reset inside IC. The V pulse and an internal VD pulse
constitute PLL. The V-phase comparison output signal (at pin 23 of IC204) is passed through
a low-pass filter around IC503 and reflected on internal master VCXO (around IC504).
2-2-5. DC Servo Circuit
The DC servo circuit controls the drive signal (at pin 1 of IC402) for auto iris lens driving from a
microcomputer (IC304) through EVR (IC301).
2-2-6. Motor Drive Circuit
The motor drive circuit controls a stepping motor-driven driver (IC309) from microcomputer IC304 so as
to switch the infrared cut-off filter and glass placed in front of CCD.
2-2-7. Character Generator Circuit
The character generator circuit controls character signal B (IC307) for menu display from microcomputer
IC304.

2-3. FC-92 Board
2-3-1. RS-485 Communication Circuit
The RS-485 communication circuit mainly consists of IC701.
2-3-2. Function Selection Switches
An address DIP switch (S706) for RS-485 communication and menu tactile switches (S701 to S705) are
provided.
2-3-3. I/O Circuit
The I/O circuit sends the external I/O signal of CN701, connected with the CT-221 board on the rear
panel, through a floating circuit (around PH703).
2-3-4. CT-221 Board
The CT-221 board mounts a terminal board, connector board, and fuse. (The fuse is mounted only on the
SSC-DC690.)
