Z86230—PRELIMINARY
TANDARD
Conditions
Phase Step (Head Switch) ±10 µs maximum
Fh Deviation (long term) ±0.5% maximum
Fh p-p Deviation (short term) ±0.3% maximum
The internal sync circuits lock to all 525- or 625-line
signals that exhibit a vertical sync pulse that meets the
following conditions:
The Z86230 functions down to a 25 dB signal-to-noise
ratio (CCIR-weighted) with one error per row or better
at that level.
Input
1. It is at least 3H ±0.5H wide.
2. It starts at the proper 2H boundary for its field.
3. If equalizing pulse serrations are present, they
