General Description
The CS61304A combines the complete analog transmit
and receive line interface for T1 or E1 applications in a
low power, 28-pin device operating from a +5V supply.
The CS61304A is a pin-compatible replacement for the
LXT304A.
The receiver uses a digital Delay-Locked-Loop which is
continuously calibrated from a crystal reference to pro-
vide excellent stability and jitter tolerance. The
CS61304A has a receiver jitter attenuator optimized for
T1 CPE applications subject to AT&T 62411 and E1
ISDN PRI applications. The transmitter features inter-
nal pulse shaping and a low impedance output stage
allowing the use of external resistors for transmitter im-
pedance matching.
Applications
Primary Rate ISDN Network/Termination Equipment
Channel Service Units
