4.1.2 RECEIVE SIDE PINS (cont.)
Signal Name:
RFSYNC
Signal Description:
Receive Frame Sync
Signal Type:
Output
An extracted 8 kHz pulse, one RCLK wide, is output at this pin which identifies frame boundaries.
Signal Name:
RMSYNC
Signal Description:
Receive Multiframe Sync
Signal Type:
Output
Only used when the receive side elastic store is enabled. An extracted pulse, one RSYSCLK wide, is output at this pin which
identifies multiframe boundaries. If the receive side elastic store is disabled, then this output will output multiframe boundaries
associated with RCLK.
Signal Name:
RDATA
Signal Description:
Receive Data
Signal Type:
Output
Updated on the rising edge of RCLK with the data out of the receive side framer.
Signal Name:
RSYSCLK
Signal Description:
Receive System Clock
Signal Type:
Input
1.544 MHz , 2.048 MHz , 4.096 MHz or 8.192 MHz clock. Only used when the receive side elastic store function is enabled.
Should be tied low in applications that do not use the receive side elastic store. See section 20 on page 129 for details on 4.096
MHz and 8.192 MHz operation using the Interleave Bus Option.
Signal Name:
RSIG
Signal Description:
Receive Signaling Output
Signal Type:
Output
Outputs signaling bits in a PCM format. Updated on rising edges of RCLK when the receive side elastic store is disabled.
Updated on the rising edges of RSYSCLK when the receive side elastic store is enabled.
Signal Name:
RLOS/LOTC
Signal Description:
Receive Loss of Sync / Loss of Transmit Clock
Signal Type:
Output
A dual function output that is controlled by the CCR3.5 control bit. This pin can be programmed to either toggle high when the
synchronizer is searching for the frame and multiframe or to toggle high if the TCLK pin has not been toggled for 5
msec.
Signal Name:
RCL
Signal Description:
Receive Carrier Loss
Signal Type:
Output
Set high when the line interface detects a carrier loss.
Signal Name:
RSIGF
Signal Description:
Receive Signaling Freeze
Signal Type:
Output
Set high when the signaling data is frozen via either automatic or manual intervention. Used to alert downstream equipment of
the condition.
4.1.2 RECEIVE SIDE PINS (cont.)
Signal Name:
8MCLK
Signal Description:
8 MHz Clock
Signal Type:
Output
An 8.192MHz clock output that is referenced to the clock that is output at the RCLK pin.
Signal Name:
RPOSO
Signal Description:
Receive Positive Data Input
Signal Type:
Output
