Documentation

The AFX010x family products are state-of-the-art Analog Front Ends  designed for applications requiring low power consumption, high signal integrity, high sampling rate, wide bandwidth and high level of integration. 

One AFE IC consists of four independent, highly integrated channels. Each channel includes a programmable input capacitance, a single-ended-input to differential-output Programmable Gain Amplifier (PGA), an offset DAC, an ADC and a digital processor.

All products are  pin-to-pin compatible in a standard 12 mm × 12 mm, 196-Ball BGA.

Proprietary SCCORETM technology and high level of integration enable small PCB footprint and power reduction up to 50%
  • Four channels of full PGA, Offset DAC, ADC and digital processor are contained within a 12 mm × 12 mm, 196-ball BGA package
  • On-chip clock synthesizer and voltage reference
  • Low power consumption, 425 mW/channel at 5 GS/s sampling-rate
