External Hardware Control Bit. In this mode, OUTA and OUTB can be used as simple
control pins for external circuitry. Use OA4 and OB4 to toggle OUTA and OUTB.
RCLK. Receive recovered clock.
Receive Loss-of-Sync Indicator. Real-time hardware version of SR1.0
Receive Loss-of-Carrier Indicator. Real-time hardware version of SR1.1
Receive Remote Alarm Indicator. Real-time hardware version of SR1.2
Receive Unframed All-Ones Indicator. Real-time hardware version of SR1.3
Receive Slip-Occurrence Indicator. One-clock-wide pulse for every slip of the receive
elastic store. Hardware version of SR1.4.
Receive CRC Error Indicator. One-clock-wide pulse for every multiframe that contains a
CRC error. Output forced to 0 during loss of sync.
Loss-of-Transmit Clock Indicator. Real-time hardware version SR2.2
RFSYNC. Recovered frame-sync pulse.
PRBS Bit Error. A half-clock-wide pulse for every bit error in the received PRBS pattern.
TDATA/RDATA. OUTB outputs an NRZ version of the transmit data stream (TDATA) prior
to the transmit line interface. OUTA outputs the received serial data stream (RDATA) prior
to the elastic store.
Receive CRC4 Multiframe Sync. Recovered CRC4 MF sync pulse.
Receive CAS Multiframe Sync. Recovered CAS MF sync pulse.
Transmit Current Limit. Real-time indicator that the TTIP and TRING outputs have
reached their 50mA current limit.
TPOS/TNEG Output. This mode outputs the AMI/HDB3 encoded transmit data. OUTA
outputs TNEG data. OUTB outputs TPOS data.
