DSC612RI3A-010JT

Overview

The DSC612RI3A-010JT is a dual-output MEMS clock generator manufactured by Microchip Technology. It operates within a supply voltage range of 1.71 V to 3.63 V and supports LVCMOS output formats at 1.8 V, 2.5 V, or 3.3 V levels. The device provides two distinct frequency outputs: 32.768 kHz and 26 MHz, with a frequency stability of ±20 ppm across the industrial temperature range of -40°C to +85°C. Packaged in a compact 6-pin VFLGA (2.5 mm x 2.0 mm) surface-mount format, it draws a maximum current of 5 mA and features a maximum duty cycle of 55%. This component utilizes advanced silicon MEMS technology for reliable clock generation.

Feature Summary

• Dual-output architecture generating both low-frequency and high-speed clock signals from a single package
• Advanced silicon MEMS technology ensures robust performance and stability compared to traditional quartz solutions
• LVCMOS output interface compatible with standard digital logic families operating at multiple voltage levels

Applications

• Clock distribution in embedded systems requiring precise timing references
• Real-time clock synchronization in consumer electronics devices
• High-speed data processing units needing stable 26 MHz reference clocks

Procurement Notes

Verify the specific suffix 'JT' indicates tape and reel packaging containing 1000 units, distinct from tube-packaged variants like 'J' or 'GT'. Confirm that the 26 MHz output frequency matches system requirements, as some datasheets may list different primary frequencies for similar part numbers. Ensure the 20 ppm stability meets the target application's jitter and phase noise specifications before finalizing procurement orders.

Selection Notes

Select this component when dual independent clock outputs are required within a minimal footprint constraint. The 2.5x2.0 mm VFLGA package suits space-sensitive designs. Verify compatibility with the target system's voltage domain, as the device supports 1.8V, 2.5V, and 3.3V operation. Consider the 20 ppm stability sufficient for general-purpose digital logic, but evaluate if tighter tolerance is needed for precision communication interfaces.

Part Context

This part belongs to the DSC612 series of professional MEMS oscillators from Microchip Technology. The series focuses on replacing traditional quartz crystals with more durable silicon-based alternatives. The DSC612 family offers various packaging options and frequency combinations, catering to diverse industrial and consumer applications requiring reliable clock sources without the fragility associated with mechanical resonators.

Replacement Considerations

Direct substitutes include other DSC612 variants such as DSC612RI3A-010J or DSC612RI3A-010GT, which share identical electrical characteristics but differ in packaging media. Cross-reference with competitor MEMS oscillators offering dual outputs and similar 20 ppm stability if supply chain constraints require alternative sourcing.
