Description
The ISL55187 (Neptune Plus) is a highly integrated System-on-a-Chip pin electronics support solution incorporating two independent channels of:
$ PMU$ DC Levels for the Pin Electronics$ Resistive LoadThe interface, the control, and the I/O are digital. All analog circuitry is inside the chip. Two complete and independent channels are integrated into each chip.
For most tester applications, except for the pin electronics, no additional analog hardware is required on a per pin basis.
Applications
- Automated Test Equipment
- Instrumentation
- ASIC Verifiers
