GENERAL DESCRIPTION
The device is a single chip PLL frequency synthesizer
designed for TV tuning systems. Control data is entered
via the I
2
C-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
I
2
C-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.
