Description
This driver module, designed for silicon photonics, contains 8 ultra-precise fully programmable channels. It uses a new card-edge connector system which is easier to use and more robust than its predecessor. Adapters are available. Next-generation fully shielded backplane, cable, and interposer infrastructure to fit the new connectors are now available. Initial quantities are limited.
Features
n 8 software-defined input/output channels
n Channels configurable as voltage output, current output, ground, voltage or current sense
n Hardware voltage and current control (12 V, 24 mA)
n 16-bit output precision (±180 μV, ±370 nA)
n 18-bit input accuracy
Output circuit diagram
Referring to the diagram, nominal performance values are as follows. Values with ‘±’ are digitisation step sizes (i.e. resolution) and also target accuracy.
