This page describes a possible prototype using the new ADS5463 FADC operating at (up to) 500MSPS. Back to Fast_WFDs

'Clocking

The clock input is differential, with self-biasing DC levels. Best driven with 50% duty cycle, AC-coupled differential input.

Options:

• 1GHz sine wave on-board oscillator, PECL divide-by-two
• External 500MHz or 1GHz sine wave input
• PLL frequency multiplier from (i.e.) 10MHz reference input

• ​Vectron i.e. ​CO-286W
  • As of 4/5/07: CO-286W 2-4pcs 1,620.00ea; 100pcs @ 444.00

12 wks lead time

• Crystek ​CVCS0-914 1GHz SAW. ~$115 at Digi-Key. Sine output.

'Analog Input

The ​THS4509 looks like a good bet.
