1.1 Features
TheTLV320AIC10/11evaluationmodule(EVM)isa daughterboardthatplugs
directlyinto the peripheralconnector of TI’sTMS320C5402DSK(DSPstarter
kit) board. The board is populated with two TLV320AIC10/11 chips and has
footprintsforsixmore.TheEVMprovidesaplatformforevaluatingthevarious
operating modes and applications of AIC10/11 devices.
TLV320AIC10/11 devices are analog interface circuits (AIC), also called mo-
dem CODECs. They have 16-bit resolution and up to 22 kilosamples per sec-
ond (KSPS) speed. The device is designed for use with TI’s TMS320C5402
digital signal processors (DSP), or any other DSP or microprocessor that fea-
turesthemultichannelbufferedserial port(McBSP)orsynchronizedserialpe-
ripheral interface (SPI).

1.2 TLV320AIC10/11 Device Block Diagram
The TLV320AIC10/11 device contains both analog-to-digital converter (ADC)
anddigital-to-analogconverter(DAC)datapaths.TheADCdatapathincludes
operational amplifiers for input signal conditioning, an input multiplexer, an
antialiasing filter, a programmable gain amplifier, a Sigma-Delta ADC, and a
decimationfilter.TheDACdatapathcomprisesaninterpolationfilter,aSigma-
Delta DAC, a low-pass reconstruction filter, a programmable gain amplifier,
and output transmit operational amplifiers. DSP interface circuitry, band-gap
voltage reference, and clock generator/control circuits are also present in the
AIC10/11 devices.
Figure 1–1 shows the block diagram of the TLV320AIC10/11 device, and
includes the signal pinouts for the AIC10/11. The signals along the left side of
theillustrationareanalogandinterfacetotheapplication.Signalsshownalong
the right side are digital and interface with the DSP and the other AIC10/11
devices and circuitry. There are four control registers (CR) in each AIC10/11
device. Each register requires configuration for proper operation.

Rx & Tx
As shown in Figure 1–2, there are four functional sections on the EVM board:
1) AIC10/11 devices and support circuits.The EVM is populated with two
AIC10/11 devices and has footprints for six more. The unpopulated
devices are illustrated with dashed lines. Also on the board are setup,
configuration, and reset circuits that interface with all AIC10/11 devices.

Introduction
2) Analog interface and support circuits. Two analog input conditioning and
scaling circuits and one analog output driving circuit are onboard for each
of the two populated AIC10/11 devices.
3) Digital interface and support circuit. The 80-pin connector from the EVM
board to the TMS320C5402 DSK motherboard is the major digital
interface circuit.
4) Power supply circuits. Power to the EVM board can be supplied from the
motherboard or from external sources by configuring the onboard
jumpers.

2.3 EVM Jumper Description
The EVM has 28 user-configured jumpers on the board to allow maximum
flexibility in design and applications for TLV320IC10/11 EVM owners. Table
2–5 describes the 28 jumpers and lists the manufacturer’s default position for
each jumper. Also, there are footprints on the board for an additional 18
jumpersassociatedwiththe6unpopulatedAIC10/11devices,U3toU8.Refer
toFigure 2–1,orthetoplayerprinted-circuitboardinChapter6, PCBoardand
Bill of Materials
, for the location of all jumpers.

2.4 EVM Switch Description
Switch array SW2 connects the six unpopulated AIC10/11 devices (U3 to U8)
to all digital data, control and configuration signals when switched to ON.
2.5 EVM Reset Button
Pressing pushbutton SW1 manually resets all onboard AIC10/11 devices.
2.6 EVM LED Description
FLAG pins of U1 and U2 control LEDs D2 and D3, respectively. The FLAG is
a digital output of the AIC10/11 device, and can be programmed by the soft-
ware driver to flash an LED on, thus indicating good communication between
the AIC10/11 and the DSP. Table 2–6 shows the relationship between
AIC10/11 device and LED.

2.7 EVM Board Power Supply
The AIC10/11 EVM board requires three separate dc power sources. These
power sources can be from the TMS320C5402 DSK motherboard or from
external power supplies.
Two analog power sources are required. The 5 V supplied to connector J4 is
used for the onboard DAA circuits and speaker output drivers. The supplied
3.3 V to 5 V to connector J3 is used for all other EVM analog circuits.
One dc power source is required for the EVM digital circuits. The EVM can be
configured for using AIC10 or AIC11 devices by setting a jumper. Select
position 2–3 of W61 for AIC10 devices, or position 1–2 for AIC11 devices.
TLV320AIC10 devices require digital I/O power of 3.3 V to 5 V (connected to
J9), and the TLV320AIC11 devices require digital I/O power of 1.1 V to 3.6 V
(typically 1.8 V) connected to J2.
