LX7730中文资料LX7730 Radiation Hardened Telemetry Controller数据手册Microchip规格书

描述 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, SAMRH707F18, 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. There is an additional 10-bit current DAC with complementary outputs. Finally, there are 8 fixed threshold bi-level inputs with logic outputs.
