DESCRIPTION
The TSA5514 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, programme the seven
output ports and set the charge-pump current. Four of these
ports can also be used as input ports (three general purpose
I/O ports, one ADC). Digital information concerning those
ports can be read out of the TSA5514 on 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 4 programmable addresses, programmed by
applying a specific voltage to AS pin. The phase comparator
operates at 7.8125 kHz when a 4 MHz crystal is used.
