Features

Description

The CD22354A and CD22357A are monolithic silicon-

gate, double-poly CMOS integrated circuits containing

the band-limiting filters and the companding A/D and D/A

conversion circuits that conform to the AT&T D3/D4

specifications and CCITT recommendations. The

CD22354A provides the AT&T µ-law and the CD22357A

provides the CCITT A-law companding characteristic.

• Meets or Exceeds All AT&T D3/D4 Specifications and CCITT

Recommendations

• Complete CODEC and Filtering Systems: No External Components

for Sample-and-Hold and Auto-Zero Functions. Receive Output Fil-

ter with (SIN X)/X Correction and Additional 8kHz Suppression

• Variable Data Clocks - From 64kHz . . . . . . . . . . . . . . . . . . . . . 2.1MHz

• Receiver Includes Power-Up Click Filter

The primary applications for the CD22354A and

CD22357A are in telephone systems. These circuits

perform the analog and digital conversions between the

subscriber loop and the PCM highway in a digital

switching system. The functional block diagram is

shown below.

• TTL or CMOS-Compatible Logic

• ESD Protection on All Inputs and Outputs

Fea-

Applications

• PABX

With flexible features, including synchronous and

asynchronous operations and variable data rates, the

CD22354A and CD22357A are ideally suited for PABX,

central office switching system, digital telephones as

well as other applications that require accurate A/D and

D/A conversions and minimal conversion time.

• Central Ofﬁce Switching Systems

• Accurate A/D and D/A Conversions

• Digital Telephones
