NON-COMMERCIAL USE ONLY. • Fast lead time Pin Functions: Product Description The NX51SA XO series is a high performance CMOS crystal oscillator family with very low jitter performance and selectable output frequencies. Depending on customers' needs, this family devices can support 2 different frequencies using the FS select pin. It supports various options including wider frequency range, 2.5V/3.3V voltage, and various stabilities. It is designed to meet the clock source specifications for communication systems, and other high performance equipment. Pin Function 1 OE Function 2 FS 3 Ground 4 Output 5 N/C 6 V DD Frequency Select Table: *Extended high frequency power decoupling is recommended (see test circuit for minimum recommendation). To ensure optimal performance, do not route RF traces beneath the package. CREATED USING CADSTD LITE FREEWARE FROM WWW.CADSTD.COM. NON-COMMERCIAL USE ONLY.
