T1/E1/J1 BITS Element

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.
