PD<7 -0>

11-16

I

Multiplexed Cb, Y, and Cr digital video input bus.

 

 

 

 

18-19

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

20

I/O

In Slave Mode (MSTR pin is low) Horizontal Synch input. In Master

HSYN

 

 

 

 

 

 

Mode (MSTR pin is high) Horizontal Synch output.

 

 

 

 

 

 

 

 

 

21

I/O

In slave mode (MSTR pin is low) Vertical Sync input. In master mode

VSYN

 

 

 

 

 

 

Vertical Sync output.

 

 

 

 

 

 

 

 

 

MSTR

I

Master Mode;

 

 

 

 

 

 

 

 

 

If this pin is high, the chip outputs horizontal and vertical sync signals.

 

 

 

 

 

 

Otherwise it receives both horizontal and vertical sync signals.

 

 

 

 

CPNT

27

I

Select either component or composite video output.

 

 

 

 

 

 

0: Simultaneous Composite and S-Video output.

 

 

 

 

 

 

1: Component video output either RGB or YCbCr determined by the

 

 

 

 

 

 

register CR0[5:4].

 

 

 

 

 

 

 

 

PDEN

1

Pedestal enable pins.

 

 

 

 

 

 

 

 

When this pin is high 7.5 IRE is added for the NTSC composite analog

 

 

 

 

 

 

output.

VREF

40

I/O

Voltage reference. It has an internal voltage reference circuit, but may

 

 

 

 

 

 

be overridden by an external voltage reference input. A 0.1 uF ceramic

 

 

 

 

 

 

capacitor is required between this pin and GND.

 

 

 

 

IREF

39

I

A resistor should be connected between this pin and GND to control the

 

 

 

 

 

 

DAC output current. The recommended value is 198 (382) ohm 1%

 

 

 

 

 

 

metal film resistor for double (single) end 75 ohm termination.

 

 

 

 

COMP

38

I

Compensation capacitor for the DAC internal reference amplifier. A 0.1

 

 

 

 

 

 

uF ceramic capacitor is required between this pin and VDDA.

 

 

 

 

BIAS

37

I/O

DAC bias voltage. A 0.1 uf ceramic capacitor must be used to de-

 

 

 

 

 

 

couple this pin to VDDA.
