📥 Download Datasheet

General Description

TSA5512 The TSA5512 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.
