Notes:
2. Device operates to the following specs, which are guaranteed by design.
3. Increased tolerance available from pull range less than ±120 ppm.
4. ECX-5953 Series crystal orderable from Ecliptek Corporation. Please refer to the CY22388/89/91 data sheet for compatibility with most SMD type crystals.
5. Parameters are guaranteed by design and characterization. Not 100% tested in production. All parameters specified with fully loaded outputs.
