TSA5515T - Philips

TSA5515T 1.3 GHz bi-directional I2C-bus controlled synthesizer

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.
