MOPLL with IF AGC Amplifier

Data Sheet

November 2005

Features

•

Highly integrated mixer/oscillator PLL and IF AGC

amplifier for multi band analog/digital terrestrial

tuners and/or cable tuners

Ordering Information

ZL10060LDG1 48 Pin QFN* Trays

ZL10060LDF1 48 Pin QFN* Tape and Reel

•

Low phase noise PLL frequency synthesizer

*Pb Free Matte Tin

AGC output level detect with digital controlled

TOP threshold

-20°C to +85°C

•

>50 dB Desired/Undesired ratio without pre

filtering

Description

The ZL10060 is a 3 band MOPLL with IF AGC

amplifier. It down-converts the RF channel to a

standard IF followed by filtering and IF AGC

amplification for the digital channel. Each band

consists of a low noise preamplifier/mixer and local

oscillator with an external varactor tuned tank circuit.

An IF level detector is included for control of the RF

AGC. The Take Over Point and time constant are both

programmable.

•

Separate analog and digital IF outputs

>41 dB IF AGC Control range

Power down modes to support power reduction

initiatives

•

Four independent GPO

48 pin QFN Package

Applications

The ZL10060 has high signal level handling

performance providing excellent performance in the

presence of high level unwanted signals.

•

DVB-T receiver systems

ISDB-T receiver systems

DVB-C cable receiver systems

Terrestrial analog receivers

All chip control is via I²C bus.

If higher performance is required, an alternative part,

ZL10063 is available with image reject down

conversion.
