A wide range of high performance XO (Crystal Oscillator) features various output logic, low jitter, and low phase noise for 5G network infrastructure, data center, server, and automotive application.
Enhance your wireless communication systems with Siward's low phase noise TCXO, engineered for optimal frequency and temperature stability. Designed for optimal performance, our TCXO excels in low phase noise, tight frequency, and temperature stability, making it ideal for Wi-Fi, GPS, GNSS, IoT, 5G telecommunication, and connected consumer devices.
Our TCXO series features a noise floor of -165dBc/Hz at 100 kHz and supports various output formats, including CMOS and Clipped-sine. Available in industry-standard miniature sizes of 2.0 x 1.6 mm and 1.6 x 1.2 mm, these oscillators cover a frequency range from 26 MHz to 80 MHz. They offer a stability of ±0.5ppm and operate within a temperature range of -40°C to +85°C.
A series of VCTCXO (Voltage Controlled Temperature Compensated Crystal Oscillator) with great stability in compact package size range from 2.5 x 2.0 to 1.6 x 1.2 mm, widely used in GNSS/GPS, 5G network infrastructure, and automotive.Clipped-sine Output VCTCXO
