TSA5511
Information as of 2000-08-19
TSA5511; 1.3 GHz Bidirectional IC-bus controlled synthesizer
The TSA5511 is a single chip PLL frequency synthesizer designed for TV tuning systems. Control data is entered via the IC-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 TSA5511 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 IC-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.
