TSA5512 Product details

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.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 TSA5512 on the SDA line (one status byte) durin
