511FCA-CAAG

Programmable Oscillators Overview

The Skyworks Si511FCA-CAAG is a standard crystal oscillator (XO) from the Si511 series, designed for single-frequency applications. It operates at a frequency of 200 MHz with a stability of ±20 ppm. The device utilizes a fixed crystal resonator combined with a proprietary DPLL synthesizer to generate precise clock signals. It supports a supply voltage range of 2.25 V to 2.75 V, typically centered at 2.5 V or 3.3 V depending on configuration. The output format is LVDS differential. The component is housed in a 7 mm x 5 mm surface-mount package and functions within an operating temperature range of -40°C to +85°C.

Programmable Oscillators Procurement Notes

Verify the specific suffix requirements against the official datasheet, as ordering codes determine voltage, output format, and packaging. Confirm that the 7x5 mm package footprint matches the PCB design. Ensure the selected variant meets the required frequency tolerance and temperature range for the target application environment before finalizing the purchase order.

Programmable Oscillators Selection Notes

Select this model when a stable, low-jitter LVDS clock signal is required at 200 MHz. Consider the Si511 series benefits over discrete crystal solutions for improved shock resistance and simplified BOM. Verify compatibility with the system's power supply voltage and ensure the OE pin logic polarity matches the control circuitry requirements.

Programmable Oscillators Part Context

The Si511FCA-CAAG belongs to the Si511 family of programmable oscillators. This series replaces traditional XO designs by using a single crystal and IC-based synthesis to cover a wide frequency range. The 'FCA' designation indicates the 7x5 mm package size and specific output characteristics within the broader product line.

Programmable Oscillators Replacement Considerations

Publicly confirmed parameter-equivalent substitutes include the 510FCA100M000BAGR and 511FCA100M000BAGR. These alternatives share similar form factors and interface types but may differ in specific frequency or voltage configurations; verify datasheet alignment before substitution.
