GENERAL DESCRIPTION

FEATURES

The DS26503 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 6312kHz Japanese Synchronization

receiver portion can recover a clock from T1, Interface Compliant

E1, and 6312kHz synchronization timing ꢀ Interfaces to Standard T1/J1 (1.544MHz) and

interfaces. In T1 and E1 modes, the E1 (2.048MHz)

Synchronization Status Message (SSM) can also ꢀ Interface to CMI-Coded T1/J1 and E1

be recovered. The transmit portion can directly ꢀ Short- and Long-Haul Line Interface

interface to T1 or E1 interfaces as well as source ꢀ Transmit and Receive T1 and E1 SSM

the SSM in T1 and E1 modes. The DS26503 can

translate between any of the supported inbound ꢀ T1/E1 Jitter Attenuator with Bypass Mode

synchronization clock rates to any supported ꢀ Fully Independent Transmit and Receive

outbound rate. A separate output is provided to

source a 6312kHz clock. The device is ꢀ Internal Software-Selectable Receive- and
