When enabled, this input will sample signaling bits for insertion into outgoing PCM T1
data stream. Sampled on the falling edge of TCLK when the transmit side elastic store is
disabled. Sampled on the falling edge of TSYSCLK when the transmit side elastic store is
enabled. This function is available when FMS = 0.
FMS is tied to ground for the
DS21FF42/DS21FT42.
Signal Name:
Signal Description:
Signal Type:
Updated on the rising edge of TCLK with the bipolar data out of the transmit side formatter.
Can be programmed to source NRZ data via the Output Data Format (CCR1.6) control bit.
TPOS
Transmit Positive Data Output
Output
Signal Name:
Signal Description:
Signal Type:
Updated on the rising edge of TCLK with the bipolar data out of the transmit side formatter.
TNEG
Transmit Negative Data Output
Output
RECEIVE SIDE PINS
Signal Name:
Signal Description:
Signal Type:
Updated with either FDL data (ESF) or Fs bits (D4) or Z bits (ZBTSI) one RCLK before
the start of a frame. See Section 24 for details.
This signal is not bonded out in the
DS21FF42/DS21FT42.
RLINK
Receive Link Data
Output
Signal Name:
Signal Description:
Signal Type:
A 4 KHz or 2 KHz (ZBTSI) clock for the RLINK output.
This signal is not bonded out in
the DS21FF42/DS21FT42.
RLCLK
Receive Link Clock
Output
Signal Name:
Signal Description:
Signal Type:
A 192 KHz clock which pulses high during the LSB of each channel. Synchronous with
RCLK when the receive side elastic store is disabled. Synchronous with RSYSCLK when
the receive side elastic store is enabled. Useful for parallel to serial conversion of channel
data. This function is available when FMS = 1 (DS21Q41 emulation).
This signal is not
bonded out in the DS21FF42/DS21FT42.
RCHCLK
Receive Channel Clock
Output
Signal Name:
RCHBLK
