Part Number: LX7730-EVB

LX7730-EVB

Overview

The LX7730-EVB Evaluation Board is a hardware platform intended to speed up development with the LX7730 radiation-hardened by design spacecraft telemetry manager. The evaluation board is shipped with an FTDI  USB to serial interface adapter and a graphical user interface (GUI) which allows LX7730 registers to be controlled (written and read) from a PC. A 0.1" header allows alternative control of the LX7730 through either parallel or serial interfaces.

The LX7730-EVB's ZIF socket accepts any ceramic-packaged LX7730, and the kit includes an LX7730LMFQ-ES part.

All 64 analog signal inputs, the 8 bi-level analog comparator inputs, and the 8 bi-level logic outputs are routed to loop style test points.

The user guide includes a step-by-step tutorial which uses the GUI and minimal user equipment (a DVM, two resistors, 3 test leads). The tutorial walks an engineer in a hands-on manner through the LX7720's building blocks (comparators, DACs, ADC, sensor current sources, instrumentation amplifier, and input multiplexor) teaching both GUI and LX7730 operations.

The following are key features of the LX7730-EVB Evaluation Board:

  • Operates with any ceramic-packaged member of the LX7730 product line
  • LX7730LMFQ-ES sample part included
  • GUI and included USB  adapter provides easy read/write access to LX7730 registers
  • Parallel or serial interface register access by system controller available via a 0.1" header
  • DIP switches select parallel or serial interface
  • DIP switches select internal or external VEE supply and reference voltage
  • BNC socket for ADC clock input
  • Test points for the 64 analog signal inputs and analog grounds
  • Test points for the 8 bi-level analog comparator inputs
  • Test points for the 8 bi-level logic outputs
