S7A2505-156.250-L-X-R

Oscillators Overview

The S7A2505-156.250-L-X-R is a surface-mount crystal oscillator manufactured by Aker Technology Corp, designed for high-frequency digital clock applications. It operates at a nominal frequency of 156.25 MHz with an LVDS output signal type, providing differential signaling for reduced electromagnetic interference and improved signal integrity in high-speed data transmission environments. The device requires a supply voltage of 2.5V and features an enable/disable control function to manage power consumption during idle periods. Packaged in a compact 6-pad lead-free SMD form factor, it supports industrial temperature ranges and meets RoHS compliance standards for environmental safety.

Oscillators Feature Summary

• LVDS differential output configuration for enhanced noise immunity
• Integrated enable/disable functionality for dynamic power management
• Lead-free surface mount construction compliant with environmental directives

Oscillators Applications

• High-speed serial communication interfaces requiring precise clocking
• Data acquisition systems utilizing differential signaling protocols
• Telecommunications equipment operating at standard multiplex rates

Oscillators Procurement Notes

Verify the specific package pinout and mechanical dimensions against your PCB footprint design prior to integration. Confirm that the LVDS output voltage levels are compatible with the receiving logic inputs of your target circuitry. Ensure the supply voltage regulation meets the specified tolerance to maintain frequency stability under varying load conditions. Check for any required termination resistors or biasing networks necessary for proper LVDS signal integrity on the layout.

Oscillators Selection Notes

Select this component when differential clocking is required to minimize crosstalk in dense digital layouts. Consider the LVDS output type if the downstream receiver supports differential inputs rather than single-ended HCMOS signals. Evaluate the thermal environment to ensure operation within the specified temperature range without derating. Compare power consumption requirements against single-ended alternatives if low-power standby modes are critical for the system architecture.

Oscillators Part Context

This part belongs to the S7 series of precision oscillators from Aker Technology, which offers various output types and frequencies. The S7A2505 variant specifically targets applications needing stable, high-frequency clock sources with differential outputs. It complements other models in the lineup that may offer HCMOS or LVPECL outputs depending on the specific interface requirements of the host system.

Oscillators Replacement Considerations

Direct substitutes must match the 156.25 MHz frequency, LVDS output type, and 2.5V supply voltage. Verify pin compatibility for the 6-pad SMD package. Cross-reference with other manufacturers offering LVDS oscillators in similar footprints, ensuring electrical parameters such as rise/fall times and jitter specifications meet or exceed the original requirements.
