Overview
The two input channels on the RF employ Analog Devices
AD9226 A/D converters with 12-bit resolution at up to
65 MHz. The input signal processing chain consists of
50 Ohm input termination, a high speed low distortion
input amp, an optional programmable gain amp giving
a signal amplification range of -14 dB to +34 dB, followed
by a 7th order low-pass filter to the A/D. The twos
complement data from the A/D converters clock into 1
KWord FIFOs, which are configured to interrupt the host
card at programmable levels. Clocking is provided to
the two A/Ds using either the on-board dual channel
DDS or an external clock source.
