Table 30 - Jitter Attenuator Control Word
Jitter Attenuator Select. If one, the attenuator may be connected to either
the transmit or receive sides of the PCM 30 interface depend on bit 6 -
JAT/JAR. If zero, the jitter attenuator function is disabled.
Transmit or Receive Jitter Attenuator. If one, the jitter attenuator will
function on the transmit data. If zero, the jitter attenuator will function on the
receive data.
Jitter Attenuator FIFO Centre. When this bit is toggled the read pointer of
the jitter attenuator shall be centered. During centering the jitter in the JA
outputs is increased by 0.0625 U.I
Jitter Attenuator FIFO Depth Control Bits. These bits determine the
depth of the jitter attenuator FIFO as shown below:
Jitter Attenuator Clear bit. If one, the Jitter Attenuator, its FIFO and status
are reset. The status registers will identify the FIFO as being empty.
However, the actual bit values of the data in the JA FIFO will not be reset.
Unused.
