It uses a single Here’s the most comprehensive easy to understa nd reference guide to CB radio PLL circuits you’ll ever need. This chip is the same as above,the only diference is that this one uses a The AM models use a loop oscillator singnal and can be easily modified. Simple but detailed text and illustrations, all carefully prepared and written for the average person. These PLL’s are described elsewhere in this document. If these are combined they make up a 8 bit binary counter.

Plus all the very latest state-of-the-art devices in CB use worldwide. These are simplified illustrations showing exactly how a particular chip is used c1521 generate all IF frequencies, downmix frequencies, Clarifier and SSB offsets, etc.

This is “must” reading for every true CB hobbyist or serviceman! Please tell a friend about us!

Here’s the most comprehensive easy to understa nd reference guide to CB radio PLL circuits you’ll ever need. Used in both U. 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 binary programming. Also has a pair of MC binary adders to increase Ncode range. This Pll is now fitted to Unidens that say “Made in Malaysia” on the back panel.

Completely revised and expanded to include all the latest chip technology. Covers all the most common chassis, including: These chips use a double ROM set to deny illegal modifications.

This is the most popular PLL ever made! All the latest U. This chip uses simple 8 bit binary programming. This radio is useless without the mike controller. The SSB models are very broadbanded enabling channels. To send us an email now, click here.

This is the only reference especially written to include non-technical people and serious repairmen. Covers all the most common chassis, including: These models used the famous ‘sardine can’ type sealed PLL unit. See Order Form for prices.

The MB is used in the popular Uniden chassis. Plus all the very latest state-of-the-art devices in CB use plll. The chip cannot be modified except the LC SBB chassis which can be modified with an external oscillator x5121 mixer.

Pin 3 controls this operation. This is one of the newer ROM c5112 chips. See Secure Order Form for prices. This chip is a phase comparator and programmable divider only. As this radio is not as broadbanded as previous Unidens it might not be worth the expense of the new chip.

Professionally typeset, bound and illustrated, the big new International Edition covers all the most popular, classic PLL circuits. Used in alot of the newer Uniden ‘clone’ export radios. Simple but detailed text and illustrations, all carefully prepared and written for the average person. It has a possible channels via 10 bit BCD programming.

Professionally typeset, bound and illustrated, the big new International Edition covers all the most popular, classic PLL circuits.

It is used in conjunction with the C5112 programmable divider.

This is a very poor design. These two chips were paired to form a PLL.

Modification can be done by changing the loop mixing crystal or controlling pin 10 on the MB This chip is a clone of the MB with a few changes. No chance of modification. Like what you see on our site? The resistor near Pin9 needs to be removed and a jumper wire with a ferrite bead put in its place to reconnect power to pin 9. This will give 40 channels exactly Khz below the standard ‘FCC’ channels ie.

Can be modified slightly by changing the programming to the pins. A better mod is to change the loop mixing crystal. This chip also uses 6 bit binary programming. Now you don’t c5112 to be an electronic genius to understand PLL synthesizer circuits and frequency modifications.
