LFPTXO000268BULK

Overview

The LFPTXO000268BULK is a Temperature Compensated Crystal Oscillator (TCXO) manufactured by IQD Frequency Products. It operates at a nominal frequency of 26.8 MHz with HCMOS output format and a load capacitance of 15 pF. The device supports a supply voltage range of 2.97 V to 3.63 V, drawing a maximum current of 4 mA. It features tri-state capability and an enable/disable function. Frequency stability is specified at ±0.5 ppm over the operating temperature range of -40 °C to +85 °C. Aging is rated at 1 ppm per first year. The component utilizes a surface-mount package measuring 7.0 mm x 5.0 mm x 2.0 mm with 10 terminals.

Feature Summary

• Integrated temperature compensation circuitry ensures high frequency stability across extended industrial temperature ranges.
• Features tri-state output logic allowing for system-level bus isolation and power management via enable/disable control.
• Utilizes single-chip ASIC technology for compact surface-mount integration and low power consumption.

Applications

• Mobile communication devices requiring precise timing in compact form factors
• Industrial equipment operating in extended temperature environments
• Computing systems needing stable clock signals with low power profiles

Procurement Notes

Verify that the specific order suffix matches the required frequency tolerance and aging specifications, as these parameters vary within the CFPT-9000 series. Confirm RoHS compliance status and lead times directly with authorized distributors or IQD sales offices. Ensure the procurement documentation explicitly states the 10-pin SMD package dimensions and HCMOS output type to avoid substitution errors with ACMS or sine-wave variants.

Selection Notes

Select this model when a 26.8 MHz clock signal is required with sub-ppm stability over a wide temperature range. The 10-pin SMD footprint suits space-constrained designs. Consider the enable/disable feature if power management is critical. Compare against other CFPT-9000 variants if different frequencies or output formats like ACMS are needed. Verify that the 4 mA max current aligns with the system's power budget constraints.

Part Context

This component belongs to the CFPT-9000 series of Surface Mount TCXOs manufactured by IQD Frequency Products. These oscillators utilize Rakon Pluto™ ASIC technology for analog compensation. The series offers various frequencies including 26.8 MHz, packaged in a 7x5mm SMD housing. They are designed for mobile and industrial applications requiring low power and high reliability.

Replacement Considerations

Direct substitutes include other IQD CFPT-9000 series parts with identical 26.8 MHz frequency, 10-pin SMD package, and HCMOS output. Verify that replacement parts match the ±0.5 ppm stability and -40°C to +85°C temperature range. Cross-reference with IQD's official cross-reference lists for equivalent part numbers.
