INTEGRATED CIRCUITS DATA SHEET TSA5515T 1.3 GHz bi-directional I2C-bus controlled synthesizer Product specification File under Integrated Circuits, IC02 November 1991 Philips Semiconductors 1.3 GHz bi-directional I2C-bus controlled synthesizer Product specification TSA5515T GENERAL DESCRIPTION The TSA5515T 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 three output ports and set the charge-pump current. A flag is set when the loop is “in-lock”. Another flag is set when a power dip occurs on the supply line. These flags are read out of the TSA5515T on SDA line (one status byte) during a READ operation. The device has 4 programmable addresses, programmed by applying a specific voltage on the AS pin. The phase comparator operates at 7.8125 kHz when a 4 MHz crystal is used.
