 The cost of the official proggrammer for the CY2077 is a significant proportion of the cost of a small niche product I want to produce.

   

Is there any other diy method of programming these chips?

There is GP Clocks Third Party Programmer's List available on website at:

   

http://www.cypress.com/?rID=14364.

   

You also have an option to contact your Local Sales Representative or Distributor Channel for programming by selecting them from the list at:

 That might be ok for the final product, but still too expensive for the protoyping phase.

   

Having the programming done through a distribution partner would be fine, again, once the protyping is done.

   

Looks like I will have to find a different product that is more easily programmed for the prototyping.

   

Thanks anyway.

Cypress assists in providing a few programmed samples for prototyping. You can create a Customer Service Case Type for the same at Support >> Technical Support >> Create a Case. You select Samples as the Inquiry Type.

   

CY2077 is an older device mainly used if you have a design based on 5V.

   

For 3.3V based designs, there are different devices and programmers involved. There are newer devices with less expensive programmers to look at for e.g CY22800, CY22801 for which there is a programmer, not much expensive.

I've looked at the Instaclock kit and found a supplier selling at a good price.

   

Having read all the datasheets etc, I am still confused as to whether either of these chips are going to produce the frequencies required. So, I have listed the main frequencies of interest in the hope that some one can confirm whether or not these chips will generate these frequencies.

   

   
    15.0007MHz   
   
    15.0000MHz   
   
    6.7834MHz   
   
    6.7841MHz   
   
    6.7866MHz   
   
    32.060MHz   
   
    8.6700MHz   
   
        
   
    8.5450MHz   
   
    8.9985MHz   
   
    9.0015MHz   
   
    8.9993MHz   
   
    12.8000MHz   
   
    21.5000MHz   
   
    28.5000MHz   
   
    35.5000MHz   
   
    43.0000MHz   
   
    42.5000MHz   
   
    43.5000MHz   
   
    44.0000MHz

When you are going with the InstaClock Kit, the CY22801 – Universal Programmable Clock Generator (UPCG) (Details at: http://www.cypress.com/?mpn=CY22801KFXC) can be easily programmed for the frequencies you have mentioned. This is a single PLL based device that can be programmed with the InstaClock Kit to your desired frequencies. The output frequency range is from 1MHz to 200MHz for a Commercial temperature grade device and 1MHz to 166MHz for an Industrial Temperature grade device.

   

    

 

   

You can cross check the frequencies by configuring a jedec file with the CyberClocks software freely downloadable at: http://www.cypress.com/?rID=14426

 Ok, I'll get one of the Instaclock kits and see how we go. My concern is that two frequencies are only 700Hz apart and that is important. No other clock gen chip seems capable of generating frequencies with that small amount of difference (according to various other manufacturers online clock calculation software).

   

I did try to install Cyberclocks, but it failed to install on either my Win64 Proffessional machine or under Virtual XP on the same machine.

   

Thanks for your help and patience.
