LP111F23CDT application field and working principle

LP111F23CDT is a low-jitter, low-power voltage-controlled crystal oscillator (VCX), suitable for use in a variety of precision timing applications. The VCXO includes a crystal resonator and a voltage-controlled oscillator circuit. Oscillation frequency and stability depend on the crystal resonator’s electrical characteristics and structure. The temperature determines the value of the resonance frequency.

The LP111F23CDT is designed for 33.3333 MHz, 4V Lockable Frequency applications. This VCXO contains an inherent 0.7psjitter (typical) principle and thus provides better jitter performance than others within the same family. It is manufactured using tier-one technologies for reliability, obsolescence, and quality. It also incorporates differential inverting, dynamic phase frequency shift and load PMOD output options for greater versatility and can also be programmed with EEPROM.

The LP111F23CDT VCXO has an operating temperature range from -40ᵒC to 100ᵒC, while the maximum voltage swing is 4V. It is provided with hysteresis disable and positive/negative output phase. The flexibility of the output phase makes it useful for addressing all types of phase adjustment applications. The device meets the RoHS2 regulations, is compliant with VPEC-T/IEC 61000-4-2/IEC61000-4-3/EN62221/EN50082-1/FCC, and is rated to be Class B conducted emissions compliant.

The LP111F23CDT is ideal for applications such as digital mobile radios, base station radios, digital television, radio broadcast, and digital audio equipment. The device also provides excellent jitter performance for voice and multimedia applications. It is suitable for microwave communications, test equipment applications, and timing circuits that require low-power and mid-level voltage operation.

The LP111F23CDT VCXO incorporates a monolithic crystal device to ensure low jitter and electrical stability. The device uses a bank of carefully selected and oscillated crystals that are mounted in series, to provide superior jitter performance. This ensures the accuracy of oscillation for the device and the ability to maintain a low jitter level over a wide range of temperatures. The oscillator also features integrated resistors that reduce power consumption and noise suppression circuitry that further helps to reduce power consumption. The device further features a crystal trim capacitor, which can be adjusted to keep the device in lock at all temperatures to control the frequency accuracy.

In summary, the LP111F23CDT is a high-performance low-jitter, low-power voltage-controlled crystal oscillator. It is suitable for a wide range of precision timing applications and uses a monolithic crystal device for low jitter performance. It features an integrated voltage trim capacitor, which can be adjusted to maintain frequency accuracy at all temperatures. Furthermore, it meets RoHS2 regulations and is compliant with various standards and rated to be Class B conducted emissions compliant.
