§ A third consecutive zero (0, 0, 0)
In E3 mode, HDB3 decoding is performed. RLCV is asserted during any RCLK cycle where the data on
RNRZ causes one of the following code violations:
§ A BPV immediately preceded by a valid pulse (B, V) or by a valid pulse and a zero (B, 0, V)
§ A BPV with the same polarity as the last BPV
§ A fourth consecutive zero (0, 0, 0, 0)
When RLCV is asserted to flag a BPV, the RNRZ pin outputs a 1. The state bit that tracks the polarity of
the last BPV is toggled on every BPV, whether part of a valid B3ZS/HDB3 codeword or not.
To support a glueless interface to a variety of neighboring components, the polarity of RCLK can be
inverted using the ICE input pin. See the ICE pin description in
Receiver Jitter Tolerance. The receiver exceeds the input jitter tolerance requirements of all
applicable telecommunication standards in
Receiver Jitter Transfer. The jitter transfer performance of the receiver, with and without the jitter
attenuator enabled, is shown in
