GENERAL DESCRIPTION
The DS26502 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, 64kHz composite clock (64KCC), 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, E1,
or 64KCC synchronization interfaces as well as
source the SSM in T1 and E1 modes. The
DS26502 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.
