12.2 Clock and Frame Synchronization Constraints
12.2.1 SBI and Telecom Buses Both 19.44 MHz
PROPRIETARY AND CONFIDENTIAL
Table 14
Depending on the modes of operation utilized, some coordination between
LREFCLK, SREFCLK, LAC1, LDC1J1V1, SDC1FP and SAC1FP is required.
Specifically, tighter constraints must be respected when supporting transparent
virtual tributaries (TVTs) or 77.76 MHz buses.
The following only applies when using the Telecom Bus. LREFCLK may be tied
low when support is limited to DS3/E3 serial line interfaces.
The rising and falling edges of LREFCLK must be aligned with a tolerance of +/-
10ns to the corresponding edges of SREFCLK.
