Description
The Lucent Technologies Microelectronics Group
T7289A DS1 Line Interface is an integrated circuit
that provides a line interface between the DS1 cross
connect (DSX) and terminal equipment circuits for
cable distances of up to 655 ft. for 22-gauge, plastic,
insulated cable (PIC). The T7289A device performs
receive-pulse regeneration, timing recovery, and
transmit-pulse shaping and equalization functions.
The device is manufactured by using low-power
CMOS technology and is available in a 28-pin, plastic
DIP or in a 28-pin, plastic SOJ package. The T7289A
device is functionally compatible with the T7289,
LC1046A, and LC1046C devices for 1.544 Mbits/s
operation but provides improved jitter transfer and
crosstalk characteristics with a selectable single-rail/
dual-rail system interface.
