Receive Sensitivity
To meet short haul requirements, the XRT83VSH28 can accept E1 signals that have been attenuated by 12dB
of flat loss. However, the XRT83VSH28 can tolerate cable loss and flat loss beyond the industry specifications.
The receive sensitivity in the short haul mode is approximately 1,800 feet without experiencing bit errors, LOF,
pattern synchronization, etc. Although data integrity is maintained, the RLOS function (if enabled) will report an
RLOS condition according to the receiver loss of signal section in this datasheet. The test configuration for
measuring the receive sensitivity is shown in Figure 8.

Interference Margin
The interference margin for the XRT83VSH28 is -15db. The test configuration for measuring the interference
margin is shown in Figure 9.

2.2.3
General Alarm Detection and Interrupt Generation
The receive path detects RLOS, AIS, QRPD and FLS. These alarms can be individually masked to prevent the
alarm from triggering an interrupt. To enable interrupt generation, the Global Interrupt Enable (GIE) bit must be
set "High" in the appropriate global register. Any time a change in status occurs (it the alarms are enabled), the
interrupt pin will pull "Low" to indicate an alarm has occurred. Once the status registers have been read, the
INT pin will return "High". The status registers are Reset Upon Read (RUR). The interrupts are categorized in
a hierarchical process block. Figure is a simplified block diagram of the interrupt generation process.
NOTE: The interrupt pin is an open-drain output that requires a 10k
external pull-up resistor.
