Jitter Attenuator
Together with a PLL and a tunable crystal attenuation of received input jitter is done in
the clock- and data-recovery and either in the received elastic buffer (2 frames) or in the
jitter attenuator “JATT“ block of figure 3. The attenuator consists of a 288 Bit FIFO. The
FIFO is placed in the transmitter and will be active if bit LIM1.JATT=1 , Remote Loop or
Xslicer mode active.
The jitter attenuator meets the jitter transfer requirements of the Rec. I.431 and
G.735/736 (refer to figure 11).

Jitter Attenuation Performance
Also the requirements of ETSI TBR12/13 will be satisfied. Insuring adequate margin
against TBR12/13 output jitter limit with 15 UI input at 20 Hz the FALC54 will start jitter
attenuation at nearly 2 Hz.
Semiconductor Group
defines the number of pulses (1 to 255) to clear the LOS alarm. Additional recovery
conditions may be programmed by register LIM2.
