GENERAL DESCRIPTION

FEATURES

Cꢀ Four Complete E1 (CEPT) PCM-30/ISDN-PRI

Transceivers

The DS21Q59 E1 quad transceiver contains all the

necessary functions for connecting to four E1 lines.

The DS21Q59 is a direct replacement for the

DS21Q50, with the addition of signaling access and

improved interrupt handling. It is composed of a line

interface unit (LIU), framer, and a TDM backplane

interface, and is controlled through an 8-bit parallel

port configured for Intel or Motorola bus operations or

serial port operation.

Cꢀ Pin Compatible with the DS21Q50

Cꢀ Long-Haul and Short-Haul Line Interfaces

Cꢀ 32-Bit or 128-Bit Crystal-Less Jitter Attenuator

Cꢀ Frames to FAS, CAS, and CRC4 Formats

Cꢀ CAS/CCS Signaling Support

Cꢀ 4MHz/8MHz/16MHz Clock Synthesizer

Cꢀ Flexible System Clock with Automatic Source

Switching on Loss-of-Clock Source

Cꢀ Two-Frame Elastic-Store Slip Buffer on the

Receive Side

Cꢀ Interleaving PCM Bus Operation Up to

16.384MHz

Cꢀ Configurable Parallel and Serial Port Operation

Cꢀ Detects and Generates Remote and AIS Alarms

Cꢀ Fully Independent Transmit and Receive

Functionality

Cꢀ Four Separate Loopback Functions

Cꢀ PRBS Generation/Detection/Error Counting

Cꢀ 3.3V Low-Power CMOS

APPLICATIONS

DSLAMs

Routers
