描述
The ISL74420SLHEV1Z evaluation board is used to easily evaluate and configure the stand-alone operation of the ISL74420SLH radiation hardened, quad-output clock fanout IC.
Featuring the hermetic version of the ISL74420SLH, the ISL74420SLHEV1Z provides users with mechanical switches for configuration. This eases user experimentation of frequency and delay selections and other configuration options. It is functionally similar to the ISL74420SLHDEMO1Z demonstration board, which is an example of a small footprint layout with SMD resistors to provide a user-defined power-up configuration. Both versions of the ISL74420SLH boards support the I2C interface, which allows for overriding the power-up pin-selected configuration.
Before starting an evaluation, the ISL74420SLH datasheet should be reviewed for detailed information about the operation, function, and performance of the device.
特性
- User-settable switches for easy selection of frequency and phase configuration
- Banana Plugs for bench supply connection to PVIN and VCCEXT inputs
- SW3 (PVIN) for power cycling to enable strapping sense connection updates
- Dual Pin 0.1 spacing connectors or coaxial routing of clock outputs
- Enables I2C access for software control on internal device registers and associated operation
