DS26504
T1/E1/J1/64KCC BITS Element
DESIGN KIT AVAILABLE
GENERAL DESCRIPTION
The DS26504 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 DS26504 can
translate between any of the supported inbound
synchronization clock rates to any supported
outbound rate. The DS26504 can also accept an 8kHz
as well as a 19.44MHz reference clock. A separate
output is provided to source a 6312kHz clock. The
device is controlled through a parallel, serial, or
hardware controller port.
