DESCRIPTION

1 analog ground

2 DC control voltage input/output to regulate the internal PLL oscillator frequency; a low-pass filter

circuit is connected to this pin

3 bias input/output to regulate the bias current of internal current control oscillator to resonate at a

specific dot frequency

4 analog power supply

5 horizontal sync input signal from flyback circuit with negative polarity

6 active LOW input to enable serial interface

7 data input of serial interface

8 clock input of serial interface

9 digital power supply

10 vertical sync input signal from flyback circuit with negative polarity

11 half tone control which outputs a logic 1 during windowing except characters are displayed; it is

used to lower the external RED, GREEN and BLUE amplifier gain to achieve a transparent

windowing effect

12 fast blanking output of OSD; active HIGH and high impedance when OSD is disabled

13 blue colour output of OSD; active HIGH and high impedance when OSD is disabled

14 green colour output of OSD; active HIGH and high impedance when OSD is disabled

15 red colour output of OSD; active HIGH and high impedance when OSD is disabled

16 digital ground
