Procurement Notes
Verify the specific frequency tolerance and aging specifications against the official IQD datasheet for LFTCXO082851BULK prior to procurement. Ensure the selected variant matches the required operating temperature range and supply voltage constraints. Confirm package dimensions and pinout compatibility with the target PCB layout. Cross-reference RoHS compliance status if environmental regulations apply to the final assembly.
Selection Notes
Select this component when high frequency stability is required in space-constrained designs. The 8-SMD no-lead package facilitates automated surface-mount assembly. Consider the ±140ppb stability metric for precision timing applications. Evaluate the 10mA current draw against system power budgets. Verify that the 3.3V supply voltage aligns with the host circuit's logic levels and power distribution network.
Part Context
The LFTCXO series represents IQD Frequency Products' line of surface-mount temperature-compensated oscillators. These components are designed for applications requiring precise timing in compact form factors. The manufacturer utilizes advanced compensation techniques to maintain frequency accuracy over wide temperature variations. This specific model belongs to a family of oscillators optimized for mobile and industrial electronics.
Replacement Considerations
Consult official substitution lists from IQD Frequency Products for verified alternatives. Ensure any replacement part matches the 10MHz frequency, HCMOS output, and 8-SMD package dimensions. Verify identical electrical characteristics including supply voltage and stability metrics before implementation.
