Sample Application Circuit (When the LC74785/M is used in conjunction with a single-chip Y/C circuit.)
No. 5520-23/24
LC74785, LC74785M
External system clock input
Crystal oscillator
External system clock input (when the pin 3 and 4 functions are modified by mask options)
Note: When a sync tip level of 1.3 V DC (CV
IN
input signal: sync tip = 1.3 V) is selected for the internal generated video signals by option settings, the
electrolytic capacitor connected to SYN
IN
must be connected with the correct polarity.
When V
DD
1 is 5.0 V, the SYN
IN
input video signal pedestal level is clamped at about 2.5 V DC.
