TV AND VCR

PLL TUNING CIRCUIT

WITH 1.3 GHz PRESCALER

The MC44818 is a tuning circuit for TV and VCR tuner applications. It

contains, on one chip, all the functions required for PLL control of a VCO.

This integrated circuit also contains a high frequency prescaler and thus can

handle frequencies up to 1.3 GHz. The MC44818 is a pin compatible drop in

replacement for the MC44817, where the only difference is the MC44818

has a fixed divide–by–8 prescaler (cannot be bypassed) and the MC44817

uses the three wire bus.

The MC44818 has a programmable 512/1024 reference divider and is

manufactured on a single silicon chip using Motorola’s high density bipolar

process, MOSAIC (Motorola Oxide Self Aligned Implanted Circuits).
