Overview
Description
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.
- 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
- Tune the 48MHz internal oscillator by ±10% with an external resistor
The ISL74420M is available in a 48-lead TQFP-EP package, with specifications covering a temperature range of −55 °C to +125 °C.
Features
- Qualified to Renesas Rad Tolerant Screening and QCI Flow (R34TB0004EU)
- PVIN supply range: 3V to 18V
- Independent clock output supply: 3V to 5.5V
- Programmable output frequency starting at 25kHz
- Internal or external clock source
- Programmable phase delay as low as 15° increments
- I²C/SMBus compatible
- I²C/SMBus or pin strapping to set frequency and phase
- TID radiation lot acceptance testing (LDR ≤10mrad(Si)/s)
- ISL74420M30NZ: 30krad(Si)
- ISL74420M50NZ: 50krad(Si)
- SEE characterization
- No DSEE for PVIN = 20.7V, VCC = 5.5V, and VCCEXT = 6.5V at 46MeV·cm²/mg
- SEFI <10μm² at 46MeV·cm²/mg
- No missing pulse SETs and frequency deviation SETs <3.6% on CLKOUTx at 46MeV·cm²/mg
Comparison
Applications
- Multiphase power converters
- Synchronizing multiple converters on one board to control EMI and crosstalk
