XRT83SL30
SINGLE-CHANNEL T1/E1/J1 SH TRANSCEIVER WITH CLOCK RECOVERY AND JITTER ATTENUATOR
REV. P1.0.4
FUNCTIONAL DESCRIPTION
The XRT83SL30 is a fully integrated single channel short-haul transceiver intended for T1, J1 or E1 systems.
Simplified block diagrams of the device are shown in
Figure 1
,
Host
mode and
Figure 2
,
Hardware
mode.
In T1 applications, the XRT83SL30 can generate five transmit pulse shapes to meet the short-haul Digital
Cross-connect (DSX-1) template requirement. It also provides programmable transmit output pulse generator
that can be used for output pulse shaping allowing performance improvement over a wide variety of conditions.
The operation and configuration of the XRT83SL30 can be controlled through a serial microprocessor
Host
interface or, by
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.
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
.
