SP5768/KG/MP1T (Tape and Reel)

•

Complete 3.0GHz single chip system

Optimised for low phase noise, with comparison

frequencies up to 4 MHz

No RF prescaler

•

Selectable reference division ratio

Reference frequency output

Description

Selectable charge pump current

Integrated loop amplifier

The SP5768 is a single chip frequency synthesiser

designed for tuning systems up to 3.0GHz and is

optimized for low phase noise with comparison

frequencies up to 4 MHz.

Four switching ports

Low power replacement for SP5658 and 5668

Downwards software compatible with SP5658

The RF programmable divider contains a front end dual

modulus 16/17 functioning over the full operating range

and allows for coarse tuning in the upconverter

application and fine tuning in the downconverter.

ESD protection, (Normal ESD handling

procedures should be observed)

Comparison frequencies are obtained either from a

crystal controlled on-chip oscillator or from an external

source. A buffered reference frequency output is also

available to drive a second SP5768.

Applications

• TV, VCR and Cable tuning systems

• Communications systems

The device also contains 4 switching ports.
