Product Overview
The 16 Slice Global Data Acquisition System (GDAS) Converter Card are used in CT scanners and other medical systems. It is a printed circuit board which processes low level current signals from 128 channels of CT X-Ray detector photodiode and convert them into 128 voltages/charge signals. This circuit board is comprised of a 2 GDAS ASICs, 32-bit floating point DSP, 100 µA bias current circuit for the GDAS ASICs, GDAS ASIC Bridge (GAB) FPGA, CAN Transceiver, I2C serial digital output temperature sensor, bootable 16 Mbit flash memory, 128 Mbit SDRAM ICs, regulators, local ferrite beads, and digital I/O circuitry. The signal from detector output is amplified by the GDAS ASIC. The flash memory holds the necessary ASICs input offset voltage trim values, firmware version, date, time, vector table, checksum, FPGA configuration file and the converter board serial number. The on board temperature sensor (U5) monitors the board ambient temperature to ensure that the board is operating in its proper temperature range. The GE product is an innovation and technology which fits well into versatile customer needs. It is manufactured using high precision techniques which helps to achieve a good surface finish as well as good product consistency. The part is diligently designed for high performance and reliability. It is securely packaged inside a high quality packing box to avoid physical damage during transit and labeled with details about the product, Quality Assurance (QA) seal and shipment details.
