Description
The ZL10100 is a fully integrated single chip mixer
oscillator with on-board low phase noise I2C bus
controlled PLL frequency synthesizer. It is intended
primarily as the down converter for application in
double conversion tuners and is compatible with HIIF
frequencies between 1 and 1.3 GHz and all standard
tuner IF output frequencies.
The device contains all elements necessary, with the
exception of local oscillator tuning network, loop filter
and crystal reference to fabricate a complete
synthesized block converter with IF amplifier,
compatible with digital and analogue requirements.
