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.
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.15.0007MHz15.0000MHz6.7834MHz6.7841MHz6.7866MHz32.060MHz8.6700MHz8.5450MHz8.9985MHz9.0015MHz8.9993MHz12.8000MHz21.5000MHz28.5000MHz35.5000MHz43.0000MHz42.5000MHz43.5000MHz44.0000MHz
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.
