2 - 12 Bit, 65 MHz A/D Channels
· 2 - 12 Bit, 65 MHz D/A Channels
· Hardware Date Packing/Unpacking for Hi-Bandwidth I/O · Transient Capture
· High-Speed Data Acquistion 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.
