290PGILFT

Clock Generators, PLLs, Frequency Synthesizers Overview

The ICS290PGILFT is a triple Phase-Locked Loop (PLL) field-programmable spread spectrum clock synthesizer manufactured by Integrated Device Technology (IDT), now part of Renesas Electronics. It generates up to eight high-quality, high-frequency clock outputs from a low-frequency crystal input. The device features One-Time Programmable (OTP) ROM for field programmability, allowing configuration of input/output frequencies and spread spectrum amounts via VersaClock software. It operates from a standard fundamental mode crystal or clock, replacing multiple discrete oscillators to save board space and cost.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

• Triple PLL architecture with field-programmable OTP ROM
• Generates up to eight high-frequency clock outputs from a single low-frequency crystal
• Supports spread spectrum clocking to reduce electromagnetic interference (EMI)
• Configurable via IDT VersaClock software for flexible output settings

Clock Generators, PLLs, Frequency Synthesizers Applications

• Systems requiring multiple reference clocks from a single source
• Applications needing spread spectrum clocking for EMI reduction
• Designs aiming to replace discrete crystals and standalone spread spectrum devices

Clock Generators, PLLs, Frequency Synthesizers Part Context

The ICS290PGILFT belongs to the ICS290 family of clock synthesizers. While IDT was acquired by Renesas Electronics, this specific component retains its original IDT designation in distribution channels. It is distinct from Renesas' own MCU and power management lines, representing legacy IDT timing products.
