STS-3/STM-1 Telecom Bus Interface Timing Information
This section presents the timing requirements for the STS-3/STM-1 Telecom Bus Interface. In particular this
section prsents the following.
1.
Identifies which edge of TxA_CLK in which the TxA_D[7:0], TxA_PL, TxA_C1J1, TxA_ALARM and
TxA_DP output pins are updated on.
2.
The clock to output delays (from the rising edge of TxA_CLK to the instant that the TxA_D[7:0], TxA_PL,
TxA_C1J1, TxA_ALARM and TxA_DP output pins are updated.
3.
Identifies which edge of RxD_CLK that the RxD_D[7:0], RxD_PL, RxD_C1J1, RxD_ALARM and
RxD_DP input pins are sampled on.
4.
The set-up time requirements (from an update in the RxD_D[7:0], RxD_PL, RxD_C1J1, RxD_ALARM
and RxD_DP input signals to the rising edge of RxD_CLK).
5.
The hold-time requirements (from the rising edge of RxD_CLK to a change in the RxD_D[7:0], RxD_PL,
RxD_C1J1, RxD_ALARM and RxD_DP input signals)
1.3.1.1
The Transmit STS-3/STM-1 Telecom Bus Interface Timing
In the Transmit STS-3/STM-1 Telecom Bus Interface, all of the signals (which are output via this Bus Interface)
are updated upon the rising edge of TxA_CLK (19.44MHz clock signal).
Figures 12 and 13 presents an illustration of the waveforms of the signals that will be output via the Transmit
STS-3/STM-1 Telecom Bus Interface, as well as the timing parameter (t1).
NOTE: The value for t1 can be found in
The TxSBFP input signal is sampled upon the rising edge of TxA_CLK by the Transmit STS-3/STM-1 Telecom
Bus Interface circuitry, as illustrated below in Figure 13.
