FOUR CHANNEL E3/DS3/STS-1 LINE INTERFACE UNIT WITH JITTER ATTENUATOR

signal (TxClk or RxClk) and clocked out of the FIFO with the dejittered clock. When the FIFO is within two bits

of overflowing or underflowing, the FIFO limit status bit, FL_n is set to “1” in the Alarm status register. Reading

this bit clears the FIFO and resets the bit into default state.

NOTE: It is recommended to select the 16-bit FIFO for delay-sensitive applications as well as for removing smaller amounts

of jitter. Table 13 specifies the jitter transfer mask requirements for various data rates:

The jitter attenuator in the XRT75L04 meets the latest jitter attenuation specifications and/or jitter transfer

characteristics as shown in the Figure 24.
