NAME
TYPE
FUNCTION
RCLK
O
Receive Clock. Recovered 1.544MHz (T1), 2.048MHz (E1), 6312 kHz
(G.703 Synchronization Interface), or 64 kHz (Composite Clock) clock.
RS_8K
O
Receive Sync/8kHz Clock
T1/E1 Mode: An extracted pulse, one RCLK wide, is output at this pin that
identifies either frame (IOCR1.5 = 0) or multiframe (IOCR1.5 = 1)
boundaries. If set to output frame boundaries, then through IOCR1.6, RS_8K
can also be set to output double-wide pulses on signaling frames in T1 mode.
64KCC Mode: This pin will output the extracted 8 kHz portion of the
composite clock signal.
6312kHz Mode: This pin will be in a high-impedance state.
400HZ
O
400Hz Clock Output
T1/E1 Mode: This pin will be in a high-impedance state.
64KCC Mode: This pin will output the 400Hz clock if enabled.
6312kHz Mode: This pin will be in a high-impedance state.
RSER
O
Receive Serial Data
T1/E1 Mode: This is the received NRZ serial data updated on rising edges of
RCLK.
64KCC Mode: This pin will be in a high-impedance state.
6312kHz Mode: This pin will be in a high-impedance state.
RLOF_CCE
O
Receive Loss Of Frame or Composite Clock Error. This output can be
configured to be a Loss Of Transmit Clock indicator via IOCR.4 when
operating in T1 or E1 mode.
T1/E1 Mode: Set when the receive synchronizer is searching for frame
alignment (RLOF mode), or set when the signal at the TCLK pin has not
transitioned for approximately 15 periods of the scaled MCLK (LOTC mode).
64KCC Mode: Active high when errors are detected in the 8kHz clock or
400Hz clock
6312kHz Mode: This pin will be in a high-impedance state.
RLOS
O
Receive Loss Of Signal
T1 Mode: High when 192 consecutive zeros detected.
E1 Mode: High when 255 consecutive zeros detected.
64KCC Mode: High when consecutive zeros detected for 130
s typically.
6312kHz Mode: High when consecutive zeros detected for 65
s typically.
RAIS
O
Receive Alarm Indication Signal
T1 Mode: Will toggle high when receive Blue Alarm is detected.
E1 Mode: Will toggle high when receive AIS is detected.
64KCC Mode: This pin will be in a high-impedance state.
6312kHz Mode: This pin will be in a high-impedance state.
