ORDERING INFORMATION

GENERAL DESCRIPTION

The TSA5511 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 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 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.

FUNCTIONAL DESCRIPTION

The TSA5511 is controlled via the two-wire I2C-bus. For programming, there is one module address (7 bits) and the R/W bit for selecting READ or WRITE mode.

WRITE mode : R/W = 0 (see Table 1)

After the address transmission (first byte), data bytes can be sent to the device. Four data bytes are required to fully program the TSA5511. The bus transceiver has an auto-increment facility which permits the programming of the TSA5511 within one single transmission (address + 4 data bytes).

The TSA5511 can also be partially programmed on the condition that the first data byte following the address is byte 2 or byte 4. The meaning of the bits in the data bytes is given in Table 1. The first bit of the first data byte transmitted indicates whether frequency data (first bit = 0) or charge pump and port information (first bit = 1) will follow. Until an I2C-bus STOP condition is sent by the controller, additional data bytes can be entered without the need to re-address the device. This allows a smooth frequency sweep for fine tuning or AFC purposes. At power-on the ports are set to the high impedance state.

The 7.8125 kHz reference frequency is obtained by dividing the output of the 4 MHz crystal oscillator by 512. Because the input of UHF/VHF signal is first divided by 8 the step size is 62.5 kHz. A 3.2 MHz crystal can offer step sizes of 50 kHz.
