ISL6262ACRZ

ISL6262ACRZ is a high-performance clock generator/distributor from Intersil (Renesas). It takes a reference clock and fans it out to multiple low-jitter clock outputs with tight skew control, making it suitable for clock trees in CPUs, FPGAs, memory interfaces, SerDes, and other synchronous systems. The device combines a precision reference, internal clock generation/conditioning, and multiple buffered outputs with selectable drive formats to support various system requirements. It supports features common in clock trees such as enable/disable for outputs and low phase noise, and is offered in a RoHS-compliant package variant (CRZ suffix). Typical uses include telecom/datacom equipment and embedded platforms needing synchronized clocks across domains. For exact specifications—number of outputs, input/output frequency ranges, jitter, drive strength, and package details—consult the ISL6262ACRZ datasheet.

ISL6262ACRZ is a dual-channel, multi‑phase PWM controller for VRMs. Key features:
- Dual-channel, multiphase buck controller with synchronous gate drive
- I2C/PMBus compatible interface for monitoring and control
- Programmable switching frequency (and optional spread spectrum)
- Current‑mode control with cycle‑by‑cycle current limit
- Per‑channel protection: overcurrent, over/under voltage, UVLO
- Thermal protection with fault reporting
- Soft‑start, output sequencing/tracking, and rail enable
- Fault/status reporting via PMBus, including PGOOD
- Small-footprint package (ACRZ) suitable for dense VRM designs
Note: exact pinout, timing, and electrical specs vary by revision; consult the latest datasheet for precise values.

- Pin count: 28 pins (ISL6262ACRZ is a 28‑pin device).
- Function: Dual/ multiphase buck regulator PWM controller for VRMs. Provides oscillator, dual error amplifiers, current-sense inputs, enable/soft-start, protection features, and two PWM outputs to drive external MOSFETs for CPU core voltage regulation.
