It is used in conjunction with the MSL programmable divider. To send us an email now, click here.

Please tell a friend about us! These are simplified illustrations showing exactly how a particular chip is used to generate all IF frequencies, downmix frequencies, Clarifier and SSB offsets, etc. No chance of modification. Covers all the most common chassis, including: This is “must” reading for every true CB hobbyist or serviceman!

Used in alot of the newer Uniden ‘clone’ export radios. As this radio is not as broadbanded as previous Unidens it might not be worth c511 expense of the new chip. The MB is used in the popular Uniden chassis.

RigPix Database – Components and datasheets – PLL and DDS circuits

AM models can be modified by changing the programming or loop mixing crystal. Modification can be done by changing the loop mixing crystals or a better method is to change the BCD programming. We’ve combined hundreds of CB models and years c51221 PLL experience into a single handy reference source. Now you don’t have to be an electronic genius to understand PLL synthesizer circuits and frequency modifications. The resistor plk Pin9 needs to be removed and a jumper wire with a ferrite bead put in its place to reconnect power to pin 9.

Completely revised and expanded to include all the latest chip technology. It uses a single The AM models use a loop oscillator singnal and can be easily modified.

If these are combined they make up a 8 bit binary counter.

It requires that you change both crystals to get all modes. Also included is a unique section of specially prepared PLL chassis diagrams. These models used the famous ‘sardine can’ type sealed PLL unit.

C5122 PLL Synthesizer

This is a very poor design. Here’s the most comprehensive easy to understa nd reference guide to CB radio PLL circuits you’ll ever need. A better mod is to change the loop mixing crystal. Here’s the most comprehensive easy to understa nd reference guide to CB radio PLL circuits you’ll ever need. This radio is useless without the mike controller. This chip is a phase comparator and programmable divider only.

This is one of the newer ROM type chips. Like what you see on our site? Professionally typeset, bound and illustrated, the big new International Edition covers all the most popular, classic PLL circuits. Covers all the most common chassis, including: Used in both U.

This is “must” reading for every true CB hobbyist or serviceman! Modification is done by useing an external oscillator to replace the doubled 20 Mhz mixing signal coming from the 10 Mhz reference divider. This chip uses simple 8 bit binary programming.

This Pll is now fitted to Unidens that say “Made in Malaysia” on the back panel. These PLL’s are described elsewhere in this document. Simple but detailed text and illustrations, all carefully prepared and written for the average person.

Completely revised and expanded to include all the latest chip technology.
