M665-02-AA-AEJ

Overview

The M665-02-AA-AEJ is a Voltage-Controlled SAW Oscillator (VCSO) manufactured by Renesas Electronics Corporation. It operates on a single 3.3V supply and utilizes a crystal base resonator. The device supports selectable output frequencies of 622.08 MHz and 666.5143 MHz, with a frequency stability of ±100 ppm. It is housed in a compact 6-SMD, No Lead package, also identified as CLCC-6, measuring 7.5 mm in length, 5 mm in width, and 3 mm in height. The component is rated for an operating temperature range of -40°C to 85°C.

Feature Summary

• Pin-configurable architecture allowing selection between specific high-frequency outputs via hardware settings.
• SAW-based voltage-controlled oscillation providing stable performance across the industrial temperature range.
• Compact surface-mount footprint designed for space-constrained circuit board layouts.

Applications
