HSTSS-DAC CUSTOM ICS IMPACT ON 2.75

Abstract

We analyze several telemetry data acquisition systems to gage the system impact of denser custom ICs being developed under the HSTSS-DAC project. Our baseline is a telemetry system recently developed at Eglin AFB to support 16 analog input channels, signal conditioning and encoding for Pulse Code Modulation (PCM) using Commercial Off-the- Shelf (COTS) ICs. The data acquisition portion of the system occupies three double-sided, round circuit cards, each 2.3" in diameter. A comparable system using HSTSS-DAC custom Ics will occupy only one side of one card - a factor of six-volume reduction compared to the COTS approach.
