3-CHANNEL DS3/E3/STS-1 TO STS-3/STM-1 MAPPER IC
REV. 1.0.1
NOTE:
Table 10 presents information on the Timing parameters for the Receive STS-3/STM-1 PECL Interface
These timing requirements apply to both the Primary and the Redundant Receive STS-3/STM-1 PECL
Interface blocks.

DS3/E3/STS-1 LIU INTERFACE TIMING INFORMATION
1.3.3.1
Ingress DS3/E3/STS-1 Interface Timing
The user should be aware of the following things about the Ingress DS3/E3/STS-1 Interface Timing.
1.
If a given channel is configured to operate in the DS3/E3 Mode, then the DS3/E3 Framer block can be
configured to sample the DS3/E3/STS_1_DATA_IN and the DS3/E3/STS_1_NEG_IN input pins upon
either the rising or falling edge of DS3/E3/STS_1_CLOCK.
2.
If a given channel is configured to operate in the STS-1/STM-0 Mode, then the Receive STS-1 TOH
Processor block will be operating in the Single-Rail Mode (e.g., the Receive STS-1 TOH Processor block
will ONLY sample the DS3/E3/STS_1_DATA_IN input signal.
It will not sample the DS3/E3/
STS_1_NEG_IN input signal.
3.
Further, if a given channel is configured to operate in the STS-1/STM-0 Mode, then the Receive STS-1
TOH Processor block can be configured to sample the DS3/E3/STS_1_DATA_IN input signal, upon
either the rising or falling edge of DS3/E3/STS_1_CLOCK_IN.
