DESCRIPTION
AGND
1,52,56,5
8,61
GND
Analog Ground – Ground reference and current return for analog circuitry.
AVCC
51,53,57,
64
VCC
Analog VCC – Power supply for analog circuitry. Nominally 3.3 V
A0
37
DI
The A0 configuration bit controls the HSYNC jitter fix mode of the chip.
1 : Normal mode with HSYNC fix
0 : Normal mode without HSYNC fix
BLUDAC
22
A
Analog blue output
COMP
20
A
Compensation for the internal reference amplifier. A 0.1
F capacitor should be connected between this pin
and DACVCC.
CTL[3:1]
31,32,33
DO
General-purpose control signals – Used for user defined control. In normal mode CTL1 is not powered-down
via PDO.
DACGND
24
GND
DAC ground – Ground reference and current return for the DACs.
DACVCC
19,27
VCC
DAC VCC – Power supply for the DACs. Nominally 3.3 V
DE
28
DO
Output data enable – Used to indicate time of active video display versus non-active display or blank time.
During blank, only HSYNC, VSYNC, and CTL1-3 are transmitted. During times of active display, or non-blank,
only video data, GRNDAC, REDDAC, BLUDAC is transmitted.
High : Active display time
Low: Blank time
