control circuit for nokia tv tuner 5827

Posted on Feb 7, 2014

The tuner is programmable via I ²C-Bus and provides a FBAS signal at its output. There is also the homepage of Georg Acher containing information about this tuner. I have developed a control circuit for this tuner which uses the AT89C2051 from Atmel. Operating is done via three keys: key C/P switches between the program number and the channel number, with keys + and - you can switch up or down.

The adjusted channels are stored in an EEPROM. The program or channel number is displayed on a four digit LC- or LED-Display which is controlled via I ²C-Bus.
