The Red Rapids Model 277 signal converter can supply either raw analog/digital converter (ADC) samples or complex samples produced by the embedded digital down converter, which features a tuning resolution of Fs/223 and 10 selectable octave sub-bands in addition to the full-output bandwidth of the ADC. The Model 277, designed around the Texas Instruments ADS42LB69 16-bit ADC, allows either the onboard frequency synthesizer or an external source to supply the 250 MHz sample clock. Typical applications include multichannel signal acquisition, high-speed instrumentation, signal intelligence (SIGINT) collection, software-defined radio, and signal recorder.
The Model 277 is available as a PCI Express mezzanine card (XMC), conduction-cooled mezzanine card (CCXMC), or half-length PCI Express (PCIe) adapter card. The CCXMC can be mounted to any VITA 20-2001-compliant host without modification. All form factors offer four-lane (x4) or eight-lane (x8) bus operation at Gen 2 performance. Software command, software trigger, external hardware trigger, or preset time of day can start signal acquisition, with these same options used to stop collection. The Model 277 monitors both power consumption and temperature during normal operation, with current measurements available on all of the primary voltage supplies. Temperature sensors monitor the DSP die temperature, ADC die temperature, and four additional locations on the card.
