ICS552ARI-01LF – INTEGRATED DEVICE TECHNOLOGY

The ICS552ARI-01LF is a single-channel Phase-Locked Loop (PLL) clock multiplier IC fabricated by IDT, packaged in a 20-pin QSOP (Quarter Size Outline Package). This device accepts a fundamental frequency input clock signal and generates a higher frequency output clock signal based on a programmable multiplication factor. The internal PLL circuitry utilizes a voltage-controlled oscillator (VCO) and feedback loop to achieve precise frequency multiplication with minimal jitter. The output clock signal exhibits CMOS-compatible logic levels. The device operates from a supply voltage typically in the range of 3.3V or 5V, and its operating temperature range is specified by the manufacturer’s datasheet. The ‘LF’ suffix indicates a lead-free or RoHS-compliant finish, ensuring compliance with environmental regulations. Specific multiplication ratios, input frequency range, output frequency range, and jitter performance are detailed in the manufacturer’s datasheet and are critical for proper system integration.
