GENERAL DESCRIPTION

The device is a single chip PLL frequency synthesizer

designed for TV tuning systems. Control data is entered

via the I2C-bus; five serial bytes are required to address

the device, select the oscillator frequency, program the

7 output ports and set the charge-pump current.

The output port P6 is combined with an A/D converter

input. Digital information concerning this port can be read

out of the SDA line (one status byte) during a READ

operation. A flag is set when the loop is ‘in-lock’ and is read

during a READ operation. The device has one fixed

I2C-bus address, programmed by applying a specific

voltage on AS input. The phase comparator operates at

7.8125 kHz when a 4 MHz crystal in used. The device

provides a bandswitch output to select the bands of the

mixer/oscillator ICs TDA5330, TDA5630A except

TDA5630/C1 and TDA5730 with the appropriate voltage

level.
