digital ground 1
serial clock input 1 (NVRAM)
serial data input/output 1 (NVRAM)
slave address input: LOW selects 58H; HIGH selects 60H
field polarity input: LOW selects first half line; HIGH selects second half line at the start of an
even field
horizontal sync mode control input: LOW selects HSYNC on rising edge
vertical sync mode control input. LOW selects VSYNC on rising edge
power-down imminent input: this input should be pulled LOW to indicate that the system is
about to lose power
phase-lock output: HIGH indicates that the system is phase-locked to the CVBS input
analog ground
CVBS input: this signal is applied via a 100 nF capacitor (nominal input 1 V (p-p)
this pin should be connected to ground if unused
black level input: a 100 nF capacitor should be connected to V
SSA
reference current input for analog circuits: for correct operation a 27 k
resistor should be
connected to V
SSA
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.
digital ground 2
contrast reduction: active LOW output which allows selective contrast reduction of the
television picture to enhance a mixed mode display
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
RGB reference input: drive level reference for RGB outputs
blue dot rate character output of the blue colour information: the high voltage level is defined
by the RGBREF pin (can source 4 mA)
