591DA-ADG

Programmable Oscillators Overview

The Skyworks Solutions Inc. 591DA-ADG is a standard clock oscillator from the Si591 series, designed for general-purpose applications within the 10 MHz to 810 MHz frequency range. It features a single output with an enable pin (OE P1) and supports spread spectrum functionality. The device operates on a 3.3 V supply voltage and offers a frequency stability of ±50 ppm. It is housed in a compact 6-SMD, no-lead package measuring 7 mm x 5 mm, suitable for surface-mount assembly.

Programmable Oscillators Feature Summary

• Supports spread spectrum operation for noise reduction
• Includes an active-low enable pin for power management
• Provides a single differential or single-ended output configuration

Programmable Oscillators Applications

• General-purpose clock distribution in industrial equipment
• Timing reference for communication infrastructure modules
• Clock generation for consumer electronics systems

Programmable Oscillators Procurement Notes

Verify the specific output format (LVDS, LVPECL, or CMOS) and exact operating frequency required for your design, as these parameters vary significantly across the Si591 family. Confirm that the ±50 ppm stability meets your system's jitter and phase noise requirements. Ensure the 3.3 V supply voltage aligns with your board's power rails before finalizing the component selection.

Programmable Oscillators Selection Notes

Select this model when a general-purpose oscillator with spread spectrum capability is needed. The Si591 series provides flexibility in frequency selection between 10 MHz and 810 MHz. Consider the 7x5 mm footprint for space-constrained designs. Verify compatibility with the target load capacitance and ensure the enable pin logic level matches the controlling microcontroller or FPGA.
