The DS26503 is a building-integrated timing-supply (BITS) clock-recovery element. It also functions as a basic T1/E1 transceiver. 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.
