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.
