GENERAL DESCRIPTION
The TSA5055T is a single-chip PLL frequency synthesizer
designed for satellite TV tuning systems. It may be used
with a symmetrical input (pins 13 and 14) or with an
asymmetrical input (pin 13).

required to address the device, select the oscillator
frequency, program the six output ports and set the
charge-pumpcurrent.Fouroftheseportscanalsobeused
as input ports (three general purpose I/O ports, one ADC).
Digital information concerning these ports can be read out
of the TSA5055T 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 I

C-bus address and three programmable
addresses, programmed by applying a specific voltage to
port 3. The phase comparator operates at 7.8125 kHz
when a 4 MHz crystal is used.
