The data sheet is about Philips SAA5261, SAA5262 and SAA5263 10-page intelligent teletext decoders
The Philips SAA5261, SAA5262 and SAA5263 are single‑chip 10‑page teletext decoders that integrate 625‑line (and 525‑line) TV display support, VPS, WSS, and multiple language sets. They provide automatic detection of transmitted pages, Fastext links, and TOP information, reducing PCB area and system cost.
The devices feature a high‑level command interface via an I²C‑compatible bus, backward‑compatible with the SAFARI interface, and include versatile open‑drain I/O, RGB outputs, and a single 12 MHz crystal oscillator powered from a +5 V supply.
| Digital supply voltage (Vppp) | 4.5 V – 5.5 V |
|---|---|
| Microcontroller supply current (Ipppiu) | 20 mA – 35 mA |
| Analog supply current (Ippa) | 35 mA – 50 mA |
| Teletext supply current (Ipppi) | 50 mA – 80 mA |
| Crystal frequency | 12 MHz |
| Operating temperature | -20 °C to +70 °C |
The digital supply voltage must be between 4.5 V and 5.5 V.
They are rated for ambient temperatures from –20 °C up to +70 °C.
A 12 MHz crystal oscillator is required.
