PIN DESCRIPTION
37 Vertical sync dedicated input for a TTL-level version of the vertical sync pulse. The
polarity of this pulse is programmable by register bit TXT1.V POLARITY.
38 +5 V analog power supply.
39 +5 V teletext power supply.
40 Crystal oscillator ground.
41 12 MHz crystal oscillator input.
42 12 MHz crystal oscillator output.
43 If the reset input is HIGH for 2 machine cycles (24 oscillator periods) while the oscillator
is running, the SAA5290 is reset. This pin should be connected to VDDM via a 2.2 µF
capacitor.
44 +5 V microcontroller power supply.
45 PORT 1: 8-bit open-drain bidirectional port with alternative functions. P1.0/INT1 is
46 external interrupt 1 which can be triggered on the rising and falling edge of the pulse.
47
P1.1/T0 is the counter/timer 0. P1.2/INT0 is external interrupt 0. P1.3/T1 is the
counter/timer 1. P1.6/SCL is the serial clock input for I2C-bus. P1.7/SDA is the serial
48 data port for the I2C-bus.

Notes
1. All RGB current is sourced from the RGBREF pin. The maximum effective series resistance between RGBREF and
the R, G and B pins is 150 Ω.
2. Crystal order number 4322 143 05561.
