SINGLE-CHANNEL T1/E1/J1 SH TRANSCEIVER WITH CLOCK RECOVERY AND JITTER ATTENUATOR
REV. 1.0.1
TRANSMIT AND RECEIVE TERMINATIONS
The XRT83SL30 is a versatile LIU that can be programmed to use one Bill of Materials (BOM) for worldwide
applications for T1, J1 and E1. For specific applications the internal terminations can be disabled to allow the
use of existing components and/or designs.
RECEIVER
INTERNAL RECEIVE TERMINATION MODE
In Hardware mode, RXTSEL (Pin 44) can be tied “High” to select internal termination mode or tied “Low” to
select external termination mode. By default the XRT83SL30 is set for external termination mode at power up
or at Hardware reset.
In Host mode, bit 7 in the appropriate register, (Table 19, “Microprocessor Register #1 bit description,” on
page 45), is set “High” to select the internal termination mode for the receive channel.
If the internal termination mode (RXTSEL = “1”) is selected, the effective impedance for E1, T1 or J1 can be
achieved either with an internal resistor or a combination of internal and external resistors as shown in Table 7.
