PIN DESCRIPTION
1 versatile open-drain input/output bit 0 (should be tied HIGH)
2 versatile open-drain input/output bit 1 (should be tied HIGH)
3 versatile open-drain input/output bit 2 (should be tied HIGH)
4 versatile open-drain input/output bit 3 (should be tied HIGH)
5 versatile open-drain input/output bit 4 (should be tied HIGH)
6 versatile open-drain input/output bit 5 (should be tied HIGH)
7 versatile open-drain input/output bit 6 (should be tied HIGH)
8 versatile open-drain input/output bit 7 (should be tied HIGH)

13 digital ground 1
14 serial clock input 1 (NVRAM)
15 serial data input/output 1 (NVRAM)
16 slave address input: LOW selects 58H; HIGH selects 60H
17 field polarity input: LOW selects first half line; HIGH selects second half line at the start of an
even field
18 horizontal sync mode control input: LOW selects HSYNC on rising edge
19 vertical sync mode control input. LOW selects VSYNC on rising edge
20 power-down imminent input: this input should be pulled LOW to indicate that the system is
about to lose power
21 phase-lock output: HIGH indicates that the system is phase-locked to the CVBS input
22 analog ground
23 CVBS input: this signal is applied via a 100 nF capacitor (nominal input 1 V (p-p)
24 this pin should be connected to ground if unused
25 black level input: a 100 nF capacitor should be connected to VSSA
26 reference current input for analog circuits: for correct operation a 27 kresistor should be
connected to VSSA
27 Frame output for use in non-interlaced displays: during teletext off, teletext mixed with TV
picture and subtitles this pin is inactive. In full teletext mode this pin provides a 25 Hz square
wave. FRAME = 1 = odd, FRAME = 0 = even.
28 digital ground 2
29 contrast reduction: active LOW output which allows selective contrast reduction of the
television picture to enhance a mixed mode display
30 picture on output: HIGH indicates that a TV picture is present and that the SAA526xPS is in
TV mode, mix mode, subtitle mode or news flash mode
31 RGB reference input: drive level reference for RGB outputs
32 blue dot rate character output of the blue colour information: the high voltage level is defined
by the RGBREF pin (can source 4 mA)
