Release time:

2025-07-08 13:59

In wireless communications, synchronous transmission, and distributed network control systems, oscillators are required to meet high standards in frequency accuracy, temperature range, tuning capability, and phase noise performance. The FVT-7S-WT series VCTCXO from FCom adopts a 7.0×5.0mm ceramic SMD package, supports a frequency range from 10 to 52 MHz, offers frequency stability up to ±0.1 ppm, and is available in both Clipped Sine Wave and CMOS output types. It is ideal for femtocells, compact wireless devices, and WiMAX/WLAN modules.

Key Product Features

Wide frequency output: 10 ~ 52 MHz, common values include 10 / 19.2 / 20 MHz
Superior frequency stability: ±0.1 ppm (-40°C to +95°C), or ±0.2 ppm (-40°C to +105°C)
Selectable output types: CMOS or Clipped Sine Wave
Control voltage range: 0.5V ~ 2.5V, pull range ±5.0 ppm
Excellent phase noise (@19.2 MHz):
- -100 Hz: -130 dBc/Hz
- -1 kHz: -148 dBc/Hz
- -10 kHz: -156 dBc/Hz
Fast startup time: ≤5 ms
Supply voltage options: 3.3V or 2.5V
Operating temperature: -40°C to +105°C, suitable for industrial and telecom demands
