I/O 12 Receive Serial Clock Signal (RxSERCLKn) / Receive
Line Clock (RxLINECLKn):
The exact function of these pins depends on the mode of
operation selected, as described below.
In Base-Rate Mode (1.544MHz/2.048MHz) - RxSER-
CLKn:
These pins are used as the receive serial clock on the
system side interface which can be configured as either
input or output. The receive serial interface outputs data
on RxSERn on the rising edge of RxSERCLKn.
When RxSERCLKn is configured as Input:
These pins will be inputs if the slip buffer on the Receive
path is enabled. System side equipment must provide a
1.544MHz clock rate to this input pin for T1 mode of oper-
ation, and 2.048MHz clock rate in E1 mode.
When RxSERCLKn is configured as Output:
These pins will be outputs if slip buffer is bypassed. The
receive framer will output a 1.544MHz clock rate in T1
mode of operation, and a 2.048MHz clock rate in E1
mode.
DS1/E1 High-Speed Backplane Modes* - (RxSERCLK
as INPUT ONLY)
In this mode, this pin must be used as the high-speed
input clock for the backplane interface to output high-
speed or multiplexed data on the RxSERn pin. The fre-
quency of RxSERCLK is presented in the table below.
N
OTES:
1. *High-speed backplane modes include (For T1/
E1) 2.048MVIP, 4.096MHz, 8.192MHz,
16.384MHz HMVIP, H.100, Bit-multiplexed
modes, and (For T1 only) 12.352MHz Bit-
multiplexed mode.
2. For DS1 high-speed modes, the DS-0 data is
mapped into an E1 frame by ignoring every
fourth time slot (don’t care).
