Featuring low phase noise, compact design, and compliance with rigorous military standards, these oscillators provide reliable timing solutions for radar, AESA, and other precision technologies.
Microchip Technology has introduced a new line of Voltage-Controlled SAW Oscillators (VCSOs), the 101765 series, designed for applications requiring precise signal generation and frequency control. These VCSOs operate at various frequencies, catering to the aerospace and defence sectors where signal clarity and system stability are essential. It offers phase noise performance critical for radar and other sensing technologies. These oscillators are particularly suitable for systems that rely on high-fidelity phase-locked loop timing, such as radar and instrumentation systems using Active Electronically Scanned Arrays (AESA).
The key features are:
- Operates at frequencies of 320 MHz and 400 MHz Â
- Provides phase noise performance of 166 dBc at a 10 kHz offset Â
- Features a phase noise floor of 182 dBc Â
Packaged in a compact 1-inch × 1-inch hermetic Kovar housing, the VCSOs are designed to meet the needs of applications where factors like size, weight, power consumption, and cost must be considered. They operate with a supply voltage range of 4.75–15.75V and a supply current of 111 mA, making them an efficient solution for timing requirements. For customers in aerospace and defense, the series is available with MIL-PRF-38534 screening to ensure reliability in critical applications where failure must be avoided, such as military and aerospace systems. This new VCSO family is part of the company’s growing SAW product portfolio, with options for various package configurations and support for frequencies ranging from 30 MHz to 2.7 GHz.
The company can also accommodate specific security and compliance requirements, including ITAR, EAR, and classified specifications. Test boards for these VCSOs are available to assist in the design phase. The models are currently available for purchase through the company’s sales network and authorized distributors. According to Leon Gross, corporate vice president of Microchip’s discrete products group, this new product line reflects the company’s commitment to providing low phase noise and high-performance timing products at a competitive price. These VCSOs complement the company’s broader portfolio, including components like FPGAs, MPUs, MCUs, RF, power management, and security solutions.
