GENERAL DESCRIPTION TSA5055T 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).
Control data is entered via the I2C-bus; five serial bytes are required to address the device, select the oscillator frequency, program the six 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 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 I2C-bus address and three progr...
