6 / 20 page October 1992 6 Philips Semiconductors Product specification 1.3 GHz Bidirectional I2C-bus controlled synthesizer TSA5512 PINNING FUNCTIONAL DESCRIPTION The TSA5512 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 TSA5512. The bus transceiver has an auto-increment facility which permits the programming of the TSA5512 within one single transmission (address + 4 data bytes). The TSA5512 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 purpose. 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.
