GENERAL DESCRIPTION

FEATURES

The DS26503 is a building-integrated timing-

supply (BITS) clock-recovery element. The

receiver portion can recover a clock from T1,

E1, and 6312kHz synchronization timing

interfaces. In T1 and E1 modes, the

Synchronization Status Message (SSM) can also

be recovered. The transmit portion can directly

interface to T1 or E1 interfaces as well as source

the SSM in T1 and E1 modes. The DS26503 can

translate between any of the supported inbound

synchronization clock rates to any supported

outbound rate. A separate output is provided to

source a 6312kHz clock. The device is

controlled through a parallel, serial, or hardware

controller port.
