511HAA-BBAG

Programmable Oscillators Overview

The Skyworks Solutions Inc. 511HAA-BBAG is a programmable crystal oscillator (XO) from the Si511 series, designed for general-purpose clocking applications. It features HCSL output format and operates at a nominal voltage of 2.5V with a frequency stability of 50 PPM. The device supports frequencies ranging from 0.1 MHz to 250 MHz and includes an enable pin on pin 1. It is housed in a surface-mount package suitable for automated assembly.

Programmable Oscillators Feature Summary

• Programmable architecture allows customization of frequency and parameters for specific system requirements.
• HCSL output format provides low-swing differential signaling capabilities for reduced electromagnetic interference.
• Integrated enable control via Pin 1 facilitates power management and system synchronization.

Programmable Oscillators Applications

• General-purpose clock generation in embedded systems
• Data communication interface timing
• Industrial control equipment clock sources

Programmable Oscillators Procurement Notes

Verify the exact frequency specification and programming requirements prior to procurement, as this is a programmable device. Confirm that the 2.5V supply voltage aligns with your system design. Ensure compatibility with the HCSL output interface. Check lead times and minimum order quantities with authorized distributors, as availability may vary for custom-programmed units.

Programmable Oscillators Selection Notes

Select this component when a flexible, programmable clock source is required rather than a fixed-frequency oscillator. Consider the 2.5V operating voltage and HCSL output format against your target circuit's power and signal integrity needs. Compare with other Si511 variants if different voltage levels or output formats like LVDS or CMOS are preferred. Verify that the 50 PPM stability meets your application's jitter and phase noise specifications.

Programmable Oscillators Part Context

The 511HAA-BBAG belongs to the Si511 family of standard oscillators by Skyworks Solutions. This series offers single-frequency XO options with various output formats and voltage supplies. The 'HAA' suffix typically denotes HCSL output and 2.5V operation, while 'BBAG' indicates the specific package and tape/reel configuration. It serves as a versatile alternative to fixed-frequency crystals in modern digital designs.

Programmable Oscillators Replacement Considerations

Direct replacements within the Si511 family include parts with identical voltage and output format but different frequencies, such as 511HAA-xxxxxBAG. For non-programmable equivalents, verify fixed-frequency HCSL oscillators from Skyworks or competitors with matching 2.5V and 50 PPM specs. Ensure pinout compatibility, particularly the enable function location.
