512ABA000270BAG

Overview

The Skyworks Solutions Inc. 512ABA000270BAG is a standard crystal oscillator (XO) from the Si512 series, designed for precise frequency output at 148.351648 MHz or 148.5 MHz. It features LVPECL output format with a frequency stability of 25 PPM. The device operates on a 3.3 V supply voltage within a range of 2.97 V to 3.63 V, consuming 41 mA current. It utilizes a 5 mm x 3.2 mm surface-mount package and supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Dual-frequency capability supporting 148.351648 MHz and 148.5 MHz outputs
• LVPECL output format for high-speed digital applications
• Pin-configurable design for flexible integration

Applications

• High-definition video transmission systems
• Telecommunications infrastructure equipment
• Data communication interfaces requiring precise clocking

Procurement Notes

Verify the specific frequency requirement (148.351648 MHz vs. 148.5 MHz) against your system design before ordering, as these are distinct part variants within the same package. Confirm that the LVPECL output format matches your receiver input specifications. Ensure the 3.3 V supply voltage aligns with your power architecture. Check RoHS compliance status if required by your manufacturing standards. Validate the 25 PPM stability meets your jitter and phase noise budget.

Selection Notes

Select this component when dual-frequency options near 148 MHz are needed with LVPECL outputs. Consider the 5x3.2 mm footprint for space-constrained PCB layouts. Evaluate the 25 PPM stability against stricter timing requirements; lower stability parts may be needed for tighter synchronization. Compare power consumption of 41 mA against system thermal limits. Ensure the -40°C to +85°C industrial temperature range covers your operational environment.

Part Context

This part belongs to the Si512 family of standard oscillators, which offers pin-configurable solutions for various frequency and output format combinations. The Si512 series is widely used in telecommunications and datacom applications where reliable clock generation is critical. Unlike VCXOs, this XO provides fixed frequency outputs without external tuning voltage control.
