GENERAL DESCRIPTION

FEATURES

The DS26502 is a building-integrated timing- ꢀ G.703 2048kHz Synchronization Interface

supply (BITS) clock-recovery element. It also Compliant

functions as a basic T1/E1 transceiver. The ꢀ G.703 64kHz Centralized (Option A) and

receiver portion can recover a clock from T1, Codirectional Timing Interface Compliant

E1, 64kHz composite clock (64KCC), and ꢀ G.703 Appendix II 64kHz and 6312kHz

6312kHz synchronization timing interfaces. In

T1 and E1 modes, the Synchronization Status

Japanese Synchronization Interface

Compliant

Message (SSM) can also be recovered. The ꢀ Interfaces to Standard T1/J1 (1.544MHz) and

transmit portion can directly interface to T1, E1, E1 (2.048MHz)

or 64KCC synchronization interfaces as well as ꢀ Interface to CMI-Coded T1/J1 and E1

source the SSM in T1 and E1 modes. The ꢀ Short- and Long-Haul Line Interface

DS26502 can translate between any of the ꢀ Transmit and Receive T1 and E1 SSM

supported inbound synchronization clock rates to

Messages with Message Validation

any supported outbound rate. A separate output ꢀ T1/E1 Jitter Attenuator with Bypass Mode

is provided to source a 6312kHz clock. The ꢀ Fully Independent Transmit and Receive

device is controlled through a parallel, serial, or

hardware controller port.

Functionality

ꢀ

Internal Software-Selectable Receive- and

Transmit-Side Termination for

75Ω/100Ω/110Ω/120Ω T1, E1, and

Composite Clock Interfaces

Monitor Mode for Bridging Applications

Accepts 16.384MHz, 12.8MHz, 8.192MHz,
