590QC-DDG

Programmable Oscillators Overview

The Skyworks Solutions Inc. 590QC-DDG is a programmable crystal oscillator (XO) from the Si590 series, designed for high-performance clocking applications. It features a CML output format and operates at a supply voltage of 3.3 V. The device provides a frequency stability of ±20 ppm and supports an enable/disable function. Packaged in a compact 7 mm x 5 mm surface-mount footprint, it draws a maximum supply current of 110 mA and up to 75 mA when disabled. This component is suitable for systems requiring precise, programmable timing signals with low jitter characteristics.

Programmable Oscillators Feature Summary

• Programmable frequency generation capability within the specified range
• CML output interface for differential signal integrity
• Integrated enable/disable control function for power management

Programmable Oscillators Applications

• High-speed data communication interfaces
• Network synchronization equipment
• Test and measurement instrumentation

Programmable Oscillators Procurement Notes

Verify the specific programmed frequency configuration required for the application, as this is a programmable device. Confirm that the CML output format matches the receiving circuit's input requirements. Ensure the 3.3 V supply voltage aligns with the system design. Check for any specific programming tools or software needed to configure the oscillator parameters before deployment.

Programmable Oscillators Selection Notes

Select this model when a programmable solution with CML outputs is required. Compare against other Si590 variants if different supply voltages or output formats like LVDS or CMOS are needed. Consider the ±20 ppm stability requirement against stricter phase noise needs. Verify the 7x5 mm package dimensions fit the PCB layout constraints compared to smaller packages like the 5x3.2 mm option.

Programmable Oscillators Part Context

The 590QC-DDG belongs to Skyworks' Si590 family of standard oscillators. This series offers various output formats and supply voltages. The 'QC' suffix typically denotes a specific pinout or feature set within the family, while 'DDG' indicates the CML output and 3.3V operation. It complements other models like the 590CC series which may offer CMOS outputs.

Programmable Oscillators Replacement Considerations

No direct public substitute part numbers are confirmed for this specific programmable variant. Equivalent options would require matching the programmable nature, CML output, and 3.3V supply. Other Si590 models with different outputs (e.g., 590FC series for LVDS) are not electrically compatible substitutes.
