ML6411
FUNCTIONAL DESCRIPTION (Continued)
RESET DEFAULT MODE
■ UGC is set to unity gain (G
= 1 and G
= 1) to
UGCB
UGCA
either Y or C channels (see Table 4 and GNA and GNB
The ML6411 provides a RESET pin that programs the
Control Registers as described in Table 8. The RESET pin is
active HIGH. Basically, the ML6411 on RESET defaults to:
bits)
■ Input pin are set for 2V inputs on both Y and C
P-P
■ S-Video mode. Ideally, for PAL S-Video since Preset
Mode (STDA and STDB bits) is set to unity gain boost
(G
= 1) for both Y and C (see Table 2)
PRESET
■ Y is clamped to 16. C is clamped to 128 (see Table 3)
and CLPA and CLPB bits)
