Radiation Tolerant Quad Adjustable Clock Fanout for Power Management ICs

The ISL74420M is a radiation tolerant, quad-output clock fanout IC with an optional internal oscillator. It provides synchronization clocks for any application and is particularly useful in multiphase power converters.

Using this device, users can connect multiple ISL74420M devices to create more than four synchronized clocks, set division and delay options through selection pins or over an I2C/SMBus interface, configure each of the four outputs to a specific frequency division and phase delay, and tune the 48MHz internal oscillator by ± 10% with an external resistor

The ISL74420M is available in a 48-lead TQFP-EP package and operates in the −55°C to +125°C temperature range.
