[AK8854VQ]
Pin
No.
Symbol P/S¹ I/O²
Description
60 AIN4
Analog video signal input pin. Connect via 0.033 µF capacitor and
A I voltage-splitting resistors as shown in Sec. 11. If it is not used, connect
to NC.
61 VRP
A
O
Internal reference positive voltage pin for AD converter.
Connect to AVSS via ≥0.1 µF ceramic capacitor.
62 AIN5
Analog video signal input pin. Connect via 0.033 µF capacitor and
A I voltage-splitting resistors as shown in Sec. 11. If it is not used, connect
to NC.
63 AVDD
A P ^{Analog power supply pin.}
Analog video signal input pin. Connect via 0.033 µF capacitor and
64 AIN6
A I voltage-splitting resistors as shown in Sec. 11. If it is not used, connect
to NC.

If OE=H and PDN=H just after power is turned on, output pin status will be indefinite
until internal state is determined by reset sequence.
2_{In the absence of AIN signal input, output will be black data ((Y=0x10, Cb/Cr=0x80).}
(Blueback output can be obtained by register setting.)
AK8854VQ is hereafter the “AK8854”.
