Product data sheet
14.1 Fast H-lock indicator bit
14.2 Fast time constant HPLL
14.3 Fast locking mode
14.4 Odd/even detection might become unreliable with signals from video
tape recorders
The odd/even detection is a flag, available on a pin, to indicate the interlace of a video
signal; this should be independent of the type of input signal.

Issue: The H-lock indicator bit (HL_FAST, available on RTS0/RTS1 and selectable
with HLSEL via I
function.
Impact: It is not possible to use the signal HL_FAST as fast horizontal locking indicator
bit for quick source switching. This anomaly has minor impact for most video
applications since this feature will be used mainly for security applications.
Work-around: Use of the normal flag HL or HLCK instead of HL_FAST.
Issue: The damping factor of the digital horizontal PLL is too high.
Impact: It is not possible to use the new fast time constant with VCR sources due to
visible run-ins on the first lines.
Work-around: The old VCR time constant should be used.
Issue: The fast vertical locking mode VNL shows an undefined behavior which doesn’t
match the specified function.
Impact: It is not possible to use the fast vertical locking mode VNL since in some
unknown circumstances the fast locking mode needs more time for locking than the
normal mode. This anomaly has minor impact for most video applications since this
feature will be used mainly for security applications.
Work-around: No recommendations for a functional replacement of this feature.
Issue: If a signal originated from a VTR suffers from phase errors greater than 16 s,
the odd/even detection might be set onto a wrong phase, thus interrupting the actual
odd-even sequence of the input signal.
Impact: If the generated odd/even flag is being used in a succeeding signal
processing, this processing could eventually be upset due to incorrect detection.
Work-around: It should be avoided to use the detected odd/even information
whenever it cannot be assured that the input signal is of stable time base.
