Figure 5 is a 2.048 Mbps E1 TWP application using 15
Rt resistors in line with the transmit transformer to provide
high return loss and surge protection. When high return
loss is not a critical factor, a 1:1 or 1:1.26 transformer with-
out in-line resistors provides maximum power savings. The
LXT304A is shown in Hardware Mode with a typical E1/
CRC4 Framer. The hard-wired control lines for TAOS,
LLOOP and RLOOP are individually controllable, and the
LLOOP and RLOOP lines are also tied to a single control
for the Reset function. This configuration is illustrated
with a crystal in place to enable the LXT304A Jitter Atten-
uation Loop, and a single power supply bus.
