LFTVXO083215BULK

Overview

The LFTVXO083215BULK is a Voltage-Controlled Temperature-Compensated Crystal Oscillator (VCTCXO) manufactured by IQD Frequency Products. It operates at a frequency of 20 MHz with an output format of HCMOS. The device is powered by a supply voltage ranging from 3.0 V to 3.6 V, typically 3.3 V, and draws a maximum current of 10 mA. It features a frequency stability of ±140 ppb and functions within a temperature range of -40°C to +85°C. The component is housed in an 8-SMD surface-mount package with dimensions of 5.00 mm x 3.20 mm.

Feature Summary

• Integrates voltage control for precise frequency tuning via external voltage input.
• Provides high frequency stability through internal temperature compensation mechanisms.
• Delivers a robust HCMOS digital output signal suitable for standard logic interfaces.

Applications

• Precision timing systems requiring stable clock references.
• Telecommunications equipment needing low phase noise oscillators.
• Industrial control units operating in wide temperature environments.

Procurement Notes

Verify the specific ordering suffix to confirm packaging type, as bulk packaging may differ from tape-and-reel configurations. Ensure the design supports the required control voltage range for frequency adjustment. Confirm that the 8-SMD footprint matches the PCB layout constraints. Check for any RoHS compliance details if environmental regulations apply to the end product.

Selection Notes

Select this component when a compact surface-mount oscillator with voltage control capability is required. The 20 MHz frequency and HCMOS output are key selection criteria. Consider the ±140 ppb stability requirement against system jitter specifications. The wide operating temperature range makes it suitable for harsh industrial or automotive environments where standard crystals might drift.

Part Context

This part belongs to the IQXT-210 series of VCTCXOs from IQD Frequency Products. It represents a solution for applications demanding better stability than standard TCXOs but without the size and power consumption of OCXOs. The series is designed for integration into modern electronic systems requiring reliable timekeeping under varying thermal conditions.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Cross-reference with other IQD VCTCXO models only if pin compatibility and electrical parameters match exactly.
