dual-rail or single-rail mode. The bipolar violation (and B8ZS/HDB3) detectors detect violations in dual-rail and
single-rail modes, but in dual-rail mode the violations will only be reported to the Line Violation Detect Status
(LVDS) registers.
5.5.9 Receive Single-Rail Mode
Receive single-rail mode consists of the RPOS, RCLK, and CV pins on the system side. B8ZS or HDB3 decoding
is available. The Single-Rail Mode Select Register (SRMS) is used for selection of dual-rail or single-rail mode.
5.5.10 Bipolar Violation and Excessive Zero Detector
The DS26324 detects HDB3 code violations, BPVs, and excessive zero errors. The reporting of the errors is done
through the RNEGn/CVn pin in single-rail mode and the
violations are only detected in E1 mode with HDB3 encoding. The code violation detection declares an error when
a bipolar violation of the same polarity as the last bipolar violation is received.
Excessive zeros are detected if eight consecutive zeros are detected with B8ZS enabled and four consecutive
zeros are detected with HDB3 enabled. Excessive zero detection is enabled via the Excessive Zero Detect Enable
Register (EZDE) and when HDB3/B8ZS encoding/decoding is selected via the Line Code Selection Register (LCS).
The bits in the LCS, EZDE, and
