DESCRIPTION
The TSA5512 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
eight 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 TSA5512 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 one fixed I2C-bus
address and 3 programmable addresses, programmed by
applying a specific voltage on Port 3. The phase
comparator operates at 7.8125 kHz when a 4 MHz crystal
is used.
