Description

The SL2101 is a fully integrated single chip broadband

mixer oscillator with low phase noise PLL frequency

synthesizer. It is intended for use in double conversion

tuners as both the up and down converter and is

compatible with HIIF frequencies up to 1.4 GHz and all

standard tuner IF output frequencies. It also contains a

programmable power facility for use in systems where

power consumption is important.

The device contains all elements necessary, with the

exception of local oscillator tuning network, loop filter

and crystal reference to produce a complete

synthesized block converter, compatible with digital

and analogue requirements.
