Function

TPOS/TDAT[3]

TPOS/TDAT[2]

TPOS/TDAT[1]

Output R2

AA1

Transmit Positive Pulse (TPOS[3:1]). TPOS[3:1]

represent the positive pulses transmitted on the B3ZS-

encoded DS3 or HDB3-encoded E3 lines when dual-

rail output format is selected.

Transmit Data Output (TDAT[3:1]). TDAT[3:1]

represent the NRZ (unipolar) DS3 output data streams

when single rail output format is selected.

TPOS[3:1] and TDAT[3:1] are updated on the falling

edge of the associated TCLK by default but may be

enabled to be updated on the rising edge of the

associated TCLK by setting the TRISE bit in the

DS3/E3 Master Transmit Line Options register.

TPOS[3:1] and TDAT[3:1] are updated on TICLK[3:1]

rather than TCLK[3:1] when the TICLK bit in the

DS3/E3 Master Transmit Line Options register is set.

TNEG/TMFP[3]

TNEG/TMFP[2]

TNEG/TMFP[1]

Output U4

AB1

Transmit Negative Pulse (TNEG[3:1]). TNEG[3:1]

represent the negative pulses transmitted on the

B3ZS-encoded DS3 or HDB3-encoded E3 lines when

dual-rail output format is selected.

Transmit Multiframe Pulse (TMFP[3:1]). These

signals mark the transmit frame alignment when

configured for single rail operation. TMFP[3:1] indicate

the position of overhead bits in the transmit

transmission system stream, TDAT[3:1]. TMFP[3:1]

are high during the first bit (X1) of the multiframe or E3

frame.

TNEG[3:1] and TMFP[3:1] are updated on the falling

edge of the associated TCLK by default but may be

enabled to be updated on the rising edge of the

associated TCLK by setting the TRISE bit in the

DS3/E3 Master Transmit Line Options register.

TNEG[3:1] and TMFP[3:1] are updated on TICLK[3:1]

rather than TCLK[3:1] when the TICLK bit in the

DS3/E3 Master Transmit Line Options register is set.

TICLK[3]

TICLK[2]

TICLK[1]

Input

Transmit input clock (TICLK[3:1]). TICLK[3:1]

provides the transmit direction timing for the three

DS3s or E3s. TICLK[3:1] are nominally 44.736 MHz or

34.368 MHz, 50% duty cycle clocks.
