CB PLL modifications list
Used in alot of the newer Uniden ‘clone’ export radios. This chip is a phase comparator and programmable divider only. We’ve combined hundreds of CB models and years of PLL experience into a single handy reference source.
We’ve combined hundreds of CB models and years of PLL experience into a single handy reference source. Like what you see on our site? This chip uses binary programming. It has a possible channels via 10 bit BCD programming. It is used in conjunction with the MSL programmable divider. See Secure Order Form for prices.
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. Also has a pair of MC binary adders to increase Ncode range. This chip is the same as above,the only diference is that this lpl uses a These chips pl, a double ROM set to deny illegal modifications.
These two chips were paired to form a PLL.
This chip uses simple 8 bit binary programming. AM models can be modified by changing the programming or loop mixing crystal. These are simplified illustrations showing exactly how a particular chip is used to generate all IF frequencies, downmix frequencies, Clarifier and SSB offsets, etc.
Covers all the most common chassis, including: Professionally typeset, bound and illustrated, the big new International Edition covers all the most popular, classic PLL circuits. The chip cannot be modified except the LC SBB chassis which can be modified with an external oscillator and mixer.
Please tell pll friend about us! This is the most popular PLL ever made! These PLL’s are described elsewhere in this document. Used in both U. Plus all the very latest state-of-the-art devices in CB use worldwide. Here’s the most comprehensive easy to understa nd reference guide to CB radio PLL circuits you’ll ever need.
LC5121 PLL Frequency Synthesizer
This is a very poor design. Pin 3 controls this operation. It requires that you change both crystals to get all modes. Now you don’t have to be an electronic genius to understand PLL pl circuits and frequency modifications. Modification can be done by changing the loop mixing crystals or a better method is to change the BCD programming. This is one of the newer ROM type chips.
CB PLL Modifications List
Covers all the most common chassis, including: All the latest U. This radio is useless without the mike controller.
This chip also c51211 6 bit binary programming. The MB is used in the popular Uniden chassis. Professionally typeset, bound and illustrated, the big new International Edition covers all the most popular, classic PLL circuits. In the Export versions it has a pair of MC binary Adders connected to it, this enables more Ncodes per mixing crystal. It uses a single Modification is done by useing an external oscillator to replace the doubled 20 Mhz mixing signal coming from the 10 Mhz reference divider.
See Order Form for prices. This chip is a clone of the Pll with a few changes.
Completely revised and c51211 to include all the latest chip technology. Plus all the very latest state-of-the-art devices in CB use worldwide. Modification can be done by changing the loop mixing crystal or controlling pin 10 on the MB If these are combined they make up a 8 bit binary counter.
These models used the famous ‘sardine can’ type sealed PLL unit.
A better mod is to change the loop mixing crystal. This is the only reference especially written to include non-technical people and serious repairmen. To send us an email now, click here. Completely revised and expanded to ;ll all the latest chip technology. This is “must” reading for every true CB hobbyist or serviceman! This is “must” reading for every true CB hobbyist or serviceman!
