Datasheet

## S1903 and S1950 Series 

## **3.3V and 5V ACMOS/TTL, High Frequency Crystal Clock Oscillator (XO)** 

Actual Size = 5 x 7mm 

## **Product Features** 

- 3.3V or 5V ACMOS/TTL compatible logic levels 

- Very tight frequency stability available 

- Fast clock edge rate 

- Pin-compatible with standard 5x7mm packages 

- Designed for standard reflow and washing techniques 

- Pb-free and RoHS/Green compliant 

## **Product Description** 

The S19xx Series is a 3.3V or 5V crystal clock oscillator that achieves superb stability and fast rise/fall edges over a broad range of operating conditions and frequencies.  The output clock signal, generated internally with a PLL oscillator design, is compatible with ACMOS/TTL logic levels.  The device, available on tape and reel, is contained in a 5x7mm surfacemount ceramic package. 

## **Applications** 

The S19xx Series is an ideal reference clock for highspeed applications requiring tight stability, including:

Stock Shortage Specialist

When a component is unavailable, discontinued or has an unacceptable lead time, we tap into our network of vetted European and Asian distributors to source what you need — without compromising on quality or traceability.

Compliant Alternatives

We identify pin-to-pin, electrically equivalent substitutes that meet the same certifications (RoHS, AEC-Q100, REACH) as your original specification — validated against datasheets, not just part numbers. Often at a lower cost.
