TYPE
DESCRIPTION
1
MCLK1
I
Reference T1 Clock input:
This signal is an independent 1544 kHz clock with accuracy better than
+ 32 ppm and duty cycle within 40% to 60%. This clock provides timing
source for the PLL clock recovery circuit in T1 mode. This signal must be
available for the device to operate.
2
JAEN
I
Jitter Attenuator Enable:
Tie this pin “High” to enable the Jitter Attenuator. When enabled, a 32 bit
FIFO is included in the data path for all modes of operation.
NOTE: Internally Pulled down with 50 k
resistor
3
MCLK2
I
Reference E1 and 64 kHz Clock Input:
This signal is an independent 2048 kHz clock with accuracy better than +
50 ppm and duty cycle within 40% to 60%. This clock provides timing
source for the PLL clock recovery circuit in E1 and 64 kHz mode. This
signal must be available for the device to operate.
NOTE: To reduce intrinsic jitter when JA is enabled, it is recommended to
have reference clock with an accuracy of ± 25 ppm or better.
