LX7730 - 64 Analog Input Telemetry Controller

Datasheet Summary

Description

The LX7730 is a spacecraft telemetry manager that is radiation-hardened by design and works with either a space FPGA controller such as RTG4, RTAX-S/SL, and RT PolarFire, or a space MCU such as SAMRH71F20, SAMV71Q21RT, and SAM3X8ERT.

Features

  • 64 channel analog input multiplexer.
  • Break-Before-Make switching.
  • 13ksps 12-bit ADC.
  • 1% precision 5V voltage reference.
  • 3% precision adjustable current source.
  • Threshold monitoring.
  • 8 bi-level analog inputs and logic outputs.
  • 8 additional bi-level inputs from the multiplexer.
  • 10-bit DAC.
  • Parallel interface or dual SPI interface.

Production Datasheet LX7730 64 Analog Input Telemetry Controller for Space Description The LX7730 is a spacecraft telemetry manager that is radiation-hardened by design and works with either a space FPGA controller such as RTG4, RTAX-S/SL, and RT PolarFire, or a space MCU such as SAMRH71F20, SAMV71Q21RT, and SAM3X8ERT. The LX7730 contains a 64 universal input multiplexer that can be configured for a mix of differential and/or single ended sensor inputs. The internal programmable current source can be directed to any of the 64 universal inputs. The universal inputs can be acquired by the internal 12-bit ADC at a sample rate up to 13kHz. The universal inputs also function as variable bi-level inputs with the threshold set by an internal 8-bit DAC.
