A VCXO (voltage controlled crystal oscillator) is a crystal oscillator which includes a varactor diode and associated circuitry allowing the frequency to be changed by application of a voltage across that diode.

VCXO is a crystal oscillator that includes a varactor diode and associated circuitry, which allows the frequency to be changed by applying a voltage across that diode.

Available with CMOS/TTL, LVPECL, or LVDS output logic, our voltage control oscillators achieve very tight overall accuracy of ±20 ppm for a variety of applications, including WiFi, WiMax, PON, and telecommunications standards such as SONET/SDH.

The DS4077 is an integrated voltage-controlled crystal oscillator (VCXO) module designed to provide reference clock generation in base stations, telecom/datacom, and wireless applications. The DS4077 is developed using a fundamental quartz crystal plus a …

The 5076 series are miniature VCXO ICs that provide a wide frequency pulling range, even when using minia-ture crystal units for which a wide pulling range is difficult to provide.

Seiko NPC takes the lead in Voltage Controlled Oscillator IC with a broad range of CMOS, LVPECL, LVDS solutions ranging up to 250MHz for LVPECL and 170MHz CMOS and LVDS aimed at lower power and small packagin; optimum for new design of wireless, optical, and wired communications and infrastructure applications.

The PL502-00 is a monolithic low jitter and low phase noise (-125dBc @10kHz offset and 155.52MHz output), high performance CMOS VCXO IC Die, that uses a low cost crystal (12-25MHz).

What is a VCXO? Voltage Controlled Crystal Oscillator: An oscillator that uses a crystal to establish its frequency but will vary its frequency as an analog control voltage varies.

1.1. GENERAL DESCRIPTION The VCXO2H combines a Voltage Controlled High Frequency HCMOS oscillator circuitry together with an AT-cut quartz crystal in a hermetically sealed …

VCOs are used in synthesizers to generate a waveform whose pitch can be adjusted by a voltage determined by a musical keyboard or other input. A VCXO is a voltage-controlled crystal oscillator consisting of a crystal oscillator, a varactor diode, and supporting circuitry.
