LFSPXO083320

Overview

The LFSPXO083320 is a surface-mount standard clock oscillator manufactured by IQD Frequency Products. It operates at a nominal frequency of 156.25 MHz and utilizes an LVDS output format. The device requires a supply voltage ranging from 3.135 V to 3.465 V, with a typical value of 3.3 V. It features a standby function for power management and is housed in a 6-SMD, no-lead package.

Feature Summary

• Provides a stable 156.25 MHz reference signal suitable for high-speed digital interfaces
• Features LVDS output format for low-noise signal transmission
• Includes a standby control pin to reduce power consumption during inactive periods

Applications

• Reference clock source for 10G Ethernet PHY transceivers
• Clock generation for PCIe 3.0 interface circuits
• Timing reference for high-speed serial data converters (ADC/DAC)

Procurement Notes

Verify the specific suffix of the part number to confirm packaging options such as bulk or tape-and-reel quantities. Ensure the selected variant matches the required industrial temperature range and frequency stability specifications for the target application environment.

Selection Notes

Select this component when a precise 156.25 MHz timing source is required for gigabit communication standards. The LVDS output minimizes electromagnetic interference, making it suitable for dense PCB layouts. Confirm that the host circuit supports the 3.3 V logic levels and LVDS input thresholds.

Part Context

This model belongs to the LFSPXO series of surface-mount oscillators from IQD Frequency Products. These devices are designed to replace discrete crystal and oscillator circuits, offering a compact solution for modern electronics requiring reliable clock signals with minimal board space.

Replacement Considerations

Direct substitutes include other 156.25 MHz LVDS oscillators from manufacturers like Abracon or SiTime, provided they match the 6-SMD footprint and 3.3 V supply requirements.
