Vertical Count-Down
In Automatic of V C/D MODE, the vertical synchronization is controlled by internal PLL. In Fast mode, it is
synchronized with the inputted synchronizing signal and the pull-in time is short. Furthermore the time is shorter
in Very fast mode by the expanded pull-in range. Pull-in range of vertical count-down is determined by the BUS
data, V C/D MODE and V-FREQ as Table 4.

Note 3: 00, 11; Normal
Normal vertical input mode. It is good performance of vertical
phase keeping for standard TV signal sync. This mode is
recommended in the state of stability. And this mode can detect
teletext or VCR skew sync.
Note 4: 01; Teletext
This mode is less performance of vertical phase keeping for
standard TV signal sync against “Normal”. However, pull-in
speed is faster few vertical periods than “Normal”. Therefore this
mode is recommended for tesetext sync. On the other hand, this
mode can detect standard TV signal sync in the state of stability
but it is less performance of vertical phase keeping in week
signal as about 3 dB against “Normal”.
Note 5: 10; Fast
This mode is same performance of vertical phase keeping for
standard TV signal sync of “Teletext”. But it is faster pull-in
speed faster than “Teletext” because pull-in ranges wider than
“Teletext”. (refer to Table 5) Therefore, this mode is better to use
when channel changing, but is not recommended to use in the
state of stability or in week signal due to too wide pull-in range
and incorrect actions of vertical keeping appearing.
Y-DL Adjustment
Table 5 shows Y output delays against Y input on condition with BPF f
0
, Q 2.0, Y-DL Min and LPF ON.
Y-out signal can be delayed by the BUS data, Y-DL. The adjustment time of one step is 40 ns.
