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. 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. FS NX 24 SA XXXX A • Networking systems 0 Frequency 1* 1 Frequency 2* *Frequency 1 and Frequency 2 can be any frequencies within the output frequency range.
