MAX9382ESA+

Clock Generators, PLLs, Frequency Synthesizers Overview

The MAX9382ESA+ is a high-speed ECL/PECL phase-frequency detector designed for high-bandwidth phase-locked loop (PLL) applications. It compares single-ended reference and VCO inputs to produce differential up and down pulse streams. The device operates with a supply voltage range of 4.2V to 5.5V, typical supply current of 44mA, and supports frequencies up to 450MHz. It features guaranteed minimum pulse width to eliminate dead bands, ±2kV ESD protection, and internal 75kΩ input pulldown resistors. Available in 8-pin SO packages.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific ordering suffix 'ESA' corresponds to the 8-pin SO package and -40°C to +85°C temperature range as listed in the official documentation. Confirm compatibility with existing board layouts due to pin-out specifications.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select the MAX9382ESA+ for designs requiring 100K logic level compatibility and a supply voltage range of 4.2V to 5.5V. Ensure power supply bypassing uses 0.1µF and 0.01µF ceramic capacitors placed close to the device pins to maximize performance.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the MAX9382/MAX9383 family of ECL/PECL phase-frequency detectors. The MAX9382 variant specifically utilizes 100K logic levels, distinguishing it from the MAX9383 which uses 10H logic levels. Both share similar functional characteristics but differ in electrical specifications and supply voltage requirements.
