3-port E3/DS3/STS-1 LIU  
with Jitter Attenuator  
ELECTRICAL SPECIFICATIONS (continued)  
RECEIVER JITTER TRANSFER FUNCTION  
The receiver clock recovery loop characteristics are such that the receiver has the following transfer function.  
When the Jitter Attenuator (JAT) is enabled in the receive or transmit path, the receiver or transmitter will  
exhibit a jitter transfer as shown in the graph and table below. Jitter Attenuator operation is guaranteed through  
digital scan testing. The actual jitter transfer is guaranteed by logic design and is not tested during production  
testing.
