LFTCXO082837

Overview

The LFTCXO082837 is a Temperature Compensated Crystal Oscillator (TCXO) manufactured by IQD Frequency Products, belonging to the IQXT-210-31 series. It operates at a nominal frequency of 10 MHz with an HCMOS output interface and requires a 3.3V supply voltage. The device features a maximum supply current of 10 mA and offers a frequency stability of ±140 ppb. Designed for surface mount installation, it utilizes an 8-SMD, no-lead package measuring 5.00mm x 3.20mm with a maximum height of 2.20mm. The operational temperature range spans from -40°C to +85°C.

Feature Summary

• Integrates a crystal resonator with analog compensation circuitry within a single chip oscillator architecture.
• Provides stable clock signals via an HCMOS output interface suitable for digital logic integration.
• Supports extended industrial operating temperatures ranging from -40°C to +85°C.
• Features a compact surface-mount footprint designed for automated PCB assembly.

Applications

• Mobile communication devices requiring low power consumption.
• Industrial control systems operating in wide temperature environments.
• Automotive electronics applications.
• Medical instrumentation equipment.

Procurement Notes

Verify the specific order code against the manufacturer's official documentation to ensure correct frequency, stability, and package configuration. Confirm RoHS compliance status and packaging type (bulk or tape and reel) as required by your manufacturing process. Cross-reference the pinout diagram with your PCB layout to guarantee proper signal integrity and power delivery connections.

Selection Notes

Select this component when a 10 MHz reference signal with high stability is required in space-constrained designs. The 8-pin SMD package offers a smaller footprint compared to the 10-pin CFPT-9000 variants while maintaining similar performance characteristics. Ensure the system design supports the 3.3V supply rail and accommodates the specified 10 mA current draw during peak operation.

Part Context

This TCXO belongs to the IQXT-210-31 series, utilizing Pluto ASIC technology for precise frequency compensation. It represents a specialized variant within IQD's portfolio, distinct from standard VCXOs like the CFPT-9055 series which offer tuning capabilities. The part is engineered for applications demanding superior phase noise and aging performance without the need for external voltage control inputs.

Replacement Considerations

Direct substitutes include other 10 MHz HCMOS TCXOs in 8-SMD packages from the same manufacturer family. Verify that replacement parts match the ±140 ppb stability specification and -40°C to +85°C temperature range. Ensure pin compatibility and identical supply voltage requirements to maintain board-level functionality without redesign.
