STLC7546

MODEM (V.34bis) ANALOG FRONT END

GENERAL-PURPOSE SIGNAL PROCESSING

ANALOG FRONT END (AFE)

This device has a 16-bit oversampling ADC and

DAC, filtersandcontrollogicfor theserialinterface.

The oversampling frequencies for the ADC and

DAC are user programmable.

TARGETED FOR V.34bis MODEM AND

BUSINESS AUDIO APPLICATIONS

16-BIT OVERSAMPLING Σ∆ A/D AND D/A

CONVERTERS

89dB SIGNAL-TO-(NOISE+DISTORTION) RA-

TIO FOR SAMPLING FREQUENCY (FS) UP

TO 16kHz @5V

The device operation is controlled by reading the

16-bit information control register.

The major functions of the STLC7546 are :

- To convert the audio-signal to 16-bit 2’s comple-

ment data format through the ADC channel.

- To communicate with an external digital signal

processor via serial interface logic.

- To convert 16-bit 2’s complement data from a

digitalsignal processorto anaudiosignal through

the DAC channel.

94dB DYNAMIC RANGE @5V

MAX SAMPLING FREQUENCY : 45kHz

PROGRAMMABLE ADC AND DAC OVER-

SAMPLING FREQUENCIES. OVERSAM-

PLING FREQUENCY = N x 32 x FS, N = 2, 3,

4, 5, 6. THE OVERSAMPLING FREQUENCY

CAN BE FROM 0.5MHz TO 2.88MHz

MAX. SAMPLING FREQUENCY : 22.5kHz

FILTER BANDWIDTHS :

The STLC7546 consists of two signal-processing

channels, an ADC channel and a DAC channel,

and the associated digital control. The two chan-

nels operate synchronouslyso that the transmitted

data to the DAC channel and received data from

the ADC channel occur during the same timeinter-

val. The data transfer is in 2s complement format.

0.425 x THE SAMPLING FREQUENCY

ON-CHIP REFERENCE VOLTAGE

DIFFERENTIAL OUTPUT WITH PROGRAMMA-

BLE ATTENUATION : 0dB,6dB OR INFINITE

TWO SETS OF DIFFERENTIAL INPUTS WITH

PROGRAMMABLE GAINS OF 0dB AND 6dB

16-BIT SYNCHRONOUS SERIAL INTERFACE

WHOSE OPERATION IS EITHER HARDWARE

OR SOFTWARE CONTROLLABLE

To save power, e.g. in lap-top modem applications,

the low-power reset mode can be used to reduce

the power consumption to less than 1mW.

SINGLE POWER SUPPLYRANGE : 5V 5% OR

DOUBLE POWER SUPPLY : +3.3 TO 5V ±5%

DIGITALPART ; 5.0V ±5%ANALOGPART

LOW POWER CONSUMPTION : 100mW OP-

ERATING POWER AT THE NOMINAL FRE-

QUENCY OF 1.536MHz AND 5.0V SINGLE

SUPPLY (70mW @ 3.3V). LESS THAN 50µW

DESCRIPTION

TQFP44 (10 x 10 x 1.4mm)

(Thin Plastic Quad Flat Package)

ORDER CODE : STLC7546TQFP4Y

The STLC7546 is a high-resolutionanalog-to-digi-

tal and digital-to-analog converter targeted for

V.34bis modem and consumer audio applications.
