Pulse Density Violation Detector (PDVD)

The Pulse Density Violation Detection function is provided by the PDVD block.

This block detects pulse density violations of the ANSI T1.403 requirement that

there be N ones in each and every time window of 8(N+1) data bits (where N can

equal 1 through 23). The PDVD also detects periods of 16 consecutive zeros in

the incoming data. Pulse density violation detection is provided through an

internal register bit. An interrupt is generated to signal a 16 consecutive zero

event or a change of state on the pulse density violation indication.
