E3/DS3/STS-1 LINE INTERFACE UNIT
REV. 1.0.2
The HOST Mode
To configure the XRT73LC00A to operate in the HOST Mode, connect the HOST/HW input pin (pin 18) to VDD.
When the XRT73LC00A is operating in the HOST Mode, the following is true:
1. The Microprocessor Serial Interface block is enabled. Many configuration selections are made by writing
the appropriate data into the on-chip Command Registers via the Microprocessor Serial Interface.
2. All of the following input pins are disabled:
n
Pin 1 - TXLEV
n
Pin 2 - TAOS
n
Pin 12 - REQDIS
n
Pin 14 - LLB
n
Pin 15 - RLB
n
Pin 16 - STS-1/DS3
n
Pin 17 - E3
n
Pin 35 - TXOFF
Tie each of these pins to GND if the XRT73LC00A IC is to be operated in the HOST Mode.
Please see Section 5.0 for a detailed description on operating the Microprocessor Serial Interface or the on-
chip Command Registers.

SELECTING THE DATA RATE
The XRT73LC00A can be configured to support the E3 (34.368 Mbps), DS3 (44.736 Mbps) or the SONET
STS-1 (51.84 Mbps) rates. Selection of the data rate is dependent on whether the XRT73LC00A is operating
in the Hardware or HOST Mode.
A. When operating in the Hardware Mode.
To configure the XRT73LC00A for the desired data rate, the E3 and the STS-1/DS3 pins must be set to the
appropriate logic states shown in Table 2.
B. When operating in the HOST Mode.
To configure the XRT73LC00A for the desired data rate, appropriate values need to be written into the STS-1/
DS3 and E3 bit-fields in Command Register CR4.
Table 3 relates the values of these two bit-fields with respect to the selected data rates.
