E3/DS3/STS-1 LINE INTERFACE UNIT WITH SONET DESYNCHRONIZER

SERIAL HOST INTERFACE:
A flexible serial microprocessor interface is incorporated in the XRT75L00D. The interface is generic and is
designed to support the common microprocessors/microcontrollers. The XRT75L00D operates in Host mode
when the HOST/HW pin is tied “High”. The serial interface includes a serial clock (SClk), serial data input
(SDI), serial data output (SDO), chip select (CS) and interrupt output (INT). The serial interface timing is shown
in Figure 11.
The active low interrupt output signal (INT pin) indicates alarm conditions like LOS, DMO and FL to the
processor.
When the XRT75L00D is configured in Host mode, the following input pins,TxLEV, TAOS, RLB, LLB, E3, STS-
1/DS3, REQEN, JATx/Rx, JA0 and JA1 are disabled and must be connected to ground.
Table 14 below illustrates the functions of the shared pins in either Host mode or in Hardware mode.
NOTE: While configured in Host mode, the TxON input pin will be active if the TxON bit in the control register is set to “1”,
and can be used to turn on and off the transmit output drivers. This permits a system designed for redundancy to
quickly switch out a defective line card and switch-in the backup line card.
