Equivalent circuit

BU1425AK / BU1425AKV

Function

Switches between the PAL and PAL60

modes. This is effective only when

the NTB pin is HIGH. (PAL mode

only)

This switches between dividing the

VCLK input in half and using it as an

internal clock (when LOW), and using

it as an internal clock without dividing

it in half (when HIGH).

Normally, this is connected to the

GND pin. However, when 16-bit YUV

input is used, the TEST2 pin can be

used as the U and V timing control

pins.

Power supply pin for the digital, the

analog, and I / O blocks

Grounding pin for the digital and

analog blocks

Digital VDD. Equipped with pull-down

resistor.
