oscillator circuit
The ’AV420 has an internal oscillator circuit used as the 27-MHz frequency reference. Figure 14 shows a
recommended crystal circuit that needs to be connected between the ’AV420 OSCIN and OSCOUT terminals.
The circuit includes a third-overtone 27 MHz crystal, with an equivalent series resistance under 40
.
Alternatively, a 27-MHz external clock with the minimum 60/40 duty cycle can be input on the OSCIN terminal.
The accuracy and stability of the color subcarrier signal and other signals generated in the ’AV420 are directly
dependent on the accuracy and stability of the crystal circuit or the external clock.

test circuit
The ’AV420 has test terminals TEST0 through TEST4 and TOUT0 through TOUT7. These terminals are
provided for future expansion and should be either grounded (TESTs) or left unconnected (TOUTs).
