The IDE8420 is a radiation tolerant control and acquisition integrated circuit (IC) for large area hybrid imaging focal plane arrays (FPA). It is designed for use in high speed, large area focal plane applications, making it particularly suitable for MCT or InSb based applications in Earth observation and security. It integrates the functionality that is usually found in discrete proximity electronics into one radiation tolerant SoC.
Programmed via an SPI interface, NIRCA’s sequencer runs at a frequency of 0-50 MHz and controls 16 digital outputs, 16 analog outputs, and 4 LDOs supplying external units. 16 digital outputs may be controlled in a single cycle using the 256×32b digital vector memory. Analog data may be captured using sixteen 14-bit Pipeline ADCs, each with a programmable gain preamplifier input stage. Data from 8 digital inputs may also be captured, or tested generating an IRQ for a master-controller. All captured waveform data is serialized and sent upstream using LVDS and 8b/10b encoding. Adding CameraLink or Gigabit Ethernet is possible.
