描述 Description

Radiation Tolerant Telemetry Controller − Daughter BoardConnects to the RTG4 development board.The LX7730 is a spacecraft telemetry manager IC that functions as a companion to the FPGA. The LX7730 contains a 64 universal input multiplexer that can be configured as a mix of differential or single ended sensor inputs. There is a programmable current source that can be directed to any of the 64 universal inputs. The universal inputs can be sampled with a 12 bit analog-to-digital converter at a sample rate up to 13kHz. The universal inputs can also function as variable bi-level inputs with the threshold set by an internal 8 bit digital-to-analog converter. There is an additional 10 bit digital-to- analog current DAC with complementary outputs. Finally there are 8 fixed threshold bi-level inputs.The LX7730 is register programmable with 17 addressable eight bit registers. Two options are available for communication with the host FPGA. First there is an eight bit parallel bus with 5 address bits and a read/write bit that can communicate at a speed of up to 25MHz. The second option is a pair of 12.5Mbps SPI interfaces that can support redundant (alternating not simultaneous) communication to two different hosts.The LX7730 offers 1 kV ESD pin protection on FPGA interface pins and 500V ESD protection to all CH# and BLI# pins. The dielectric isolated process is failsafe. The LX7730 has enable registers that allow most of the device to be shut down to reduce power consumption and supports cold sparing on its signal pins.The controller is designed for use in rugged environments. It is packaged in a 132 pin ceramic quad flat pack and operates over a -55°C to 125°C temperature range. It is radiation tolerant to 100krad TID and 50krad ELDRs as well as single event effects.Ordering NumbersDescriptionLX7730MFQ-VRadiation Tolerant Telemetry Controller - QML Class VLX7730MFQ-QRadiation Tolerant Telemetry Controller - QML Class QLX7730-ESRadiation Tolerant Telemetry Controller - Engineering SamplesLX7730-EVBRadiation Tolerant Telemetry Controller - Evaluation BoardLX7730-DBRadiation Tolerant Telemetry Controller
