3 Description
The AFE5401-Q1 includes four channels, with each
channel comprising a low-noise amplifier (LNA), an
optional equalizer (EQ), a programmable gain
amplifier (PGA), and an antialias filter followed by a
high-speed, 12-bit, analog-to-digital converter (ADC)
at 25 MSPS per channel.
The four ADC outputs are multiplexed on a 12-bit,
parallel, CMOS-compatible output bus.
