DS26504

T1/E1/J1/64KCC BITS Element

www.maxim-ic.com

Cꢀ Transmit and Receive T1 BOC SSM Messages

with Receive Message Change of State and

Validation Indication

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.
