pin tied high). A T1/ESF Framer provides the digital interface with the host controller. Both
devices are controlled through the serial interface. In the Host mode, the LOS alarm is reported via
the serial port so the LOS pin is allowed to float.
An LXP600A Clock Adapter (CLAD) provides the 2.048 MHz system backplane clock, locked to
the recovered 1.544 MHz clock signal. The 6.176 MHz crystal across XTALIN and XTALOUT
enables the JAL that is switched to the transmit side by the Low on JASEL. Refer to
approved crystals and transformers. The power supply inputs are tied to a common bus with
appropriate decoupling capacitors (68 µF and 0.1 µF) installed on each side.
The twisted-pair interfaces are relatively simple. A 100
transformer is used on the receive side, and a pair of 12.5
1:2 output transformer.
