DS26502

T1/E1/J1/64KCC BITS Element

www.maxim-ic.com

GENERAL DESCRIPTION

FEATURES

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.
