OCTAL T1/E1/J1 SH TRANSCEIVER WITH CLOCK RECOVERY AND JITTER ATTENUATOR
FUNCTIONAL DESCRIPTION
The XRT83SL38 is a fully integrated short-haul transceiver intended for T1, J1 or E1 systems. Simplified block
In T1 applications, the XRT83SL38 can generate five transmit pulse shapes to meet the short-haul Digital
Cross-connect (DSX-1) template requirement. The operation and configuration of the XRT83SL38 can be
controlled through a parallel microprocessor Host interface or Hardware control.
MASTER CLOCK GENERATOR
Using a variety of external clock sources, the on-chip frequency synthesizer generates the T1 (1.544MHz) or
E1 (2.048MHz) master clocks necessary for the transmit pulse shaping and receive clock recovery circuit.
There are two master clock inputs MCLKE1 and MCLKT1. In systems where both T1 and E1 master clocks are
available these clocks can be connected to the respective pins. All channels of a given XRT83Sl38 must be
operated at the same clock rate, either T1, E1 or J1 modes.
In systems that have only one master clock source available (E1 or T1), that clock should be connected to both
MCLKE1 and MCLKT1 inputs for proper operation. T1 or E1 master clocks can be generated from 8kHz,
16kHz, 56kHz, 64kHz, 128kHz and 256kHz external clocks under the control of CLKSEL[2:0] inputs according
to Table 1.
NOTE: EQC[4:0] determine the T1/E1 operating mode. See
Table 5 for details.
