The IC is manufactured in bipolar technology and is designed to operate at 5 to 100 kHz channel spacing with an RF input from 50 to 1100 MHz.
The channel is programmed via a standard I2C-bus.
A low-power sensitive RF divider is incorporated together with a dead-zone eliminated, 3-state phase comparator.
The low-noise charge pump delivers 1 mA or 1/2 mA output current to enable a better compromise between fast switching and loop bandwidth.
A power-down circuit enables the synthesizer to be set to idle mode.
