I would like to hear from anybody who knows of any manufacturers out there who make fast ADCs. By fast I mean 100MSPS or faster. For example, some colleagues of mine have been using the TKAD20C from Tektronix which is an 8-bit 250MSPS chip. However, this appeared back in 87 so I'm quite certain newer technology has appeared since then. If anyone (especially company representatives) can direct me to some ADCs along with their respective manufacturer, please let me know. We are in the process of designing a high speed spectral signal indicator (ala spectrum analyzer) and I am presently evaluating the hardware currently available on the market. I'd also appreciate any comments on the DSP board I've selected which is the Viper 8704 from Impact Technologies. For those interested, I will gladly post a summary of any comments and replies I've received. Thanks in advance for your time.

I know it's slower than what you asked for, but the AD9020 and AD9060 from Analog Devices are pretty speedy. The 9020 is TTL compatible, and runs at 60 MSPS. 9060 is ECL compatible, 75 MSPS. Both devices are 10-bit A/D converters. Prices are $165 for the 9020 and $185 for the 9060. I assume AD might have some faster chips at lower resolution. Give them a call at (919) 668-9511.

In article <7812@chaph.usc.edu> cyamamot@aludra.usc.edu I write: >I would like to hear from anybody who knows of any manufacturers out there >who make fast ADCs. Well here is a list of names I've received thus far: Analog Devices Plessey Siemens Sony Tektronix TRW Looking thru some older (about 1987) data books shows Sony has/had a 250/300 MSPS ADC. Analog Devices also has a 300 MSPS ADC. I haven't called Plessey yet, but I intend to get the ADC data books from all the companies above except Tek and TRW. Tektronix is no longer in the business of making their internal parts available to the general public. They even had a 500 MSPS ADC last year but they've stated their efforts will now lean toward the business market. I'm not considering TRW because the likelihood of them keeping a part around for aftermarket maintenance is probably even less than Tektronix. We need a source who intends to keep their ADCs in their production (or even limited production) for at least several years. I'll post specific part numbers/specs/manufacturers later. Cliff Yamamoto
