Notes on operation
1) Supply de-coupling capacitors, 10nF and 4.7µF in parallel should be inserted as close to the supply pins,
2) To minimize crosstalk, attention should be given to the routing of audio and video to the IC inputs. PCB
3) Attention should be given to the electrolytic capacitors on the input and output signal pins. As the pin's
4) The audio outputs may be muted at any time after power up by connecting the HW_MUTE pin (45) to a
5) When driving video loads with impedance = 75Ω an emitter follower or video line driver is required to be

Stray capacitance on pins Vout1-8 must be kept to a minimum by placing loads as close to the pins as
possible.
