Description
The XU is a quartz-based PLL clock oscillator family with <400fs phase jitter, supporting a wide range of frequencies, input voltages, and output types. These devices are designed to operate at three different power supplies and are available in multiple package sizes as well as temperature grades.
With a patented one-time program (OTP) allowing for infinite memory shelf life, the XU devices can be programmed to generate an output frequency from 16kHz to 1500MHz with a resolution as low as 1Hz accuracy. The configuration capability of this family of devices allows for fast delivery times for both sample and large production orders.

What difference does specifying –Xunordered_cmpf to generate code?
It affects code which includes a comparison condition that would generate an invalid operation exception because the values in a floating-point comparison include NaN. The comparison conditions (fcond) of the floating-point comparison instruction (CMPF.S or CMPF.D) are changed as follows. Option specification Without With f0 == f1 ...

Would it be okay if the NC (no connect) pin on the XU crystal oscillator series (XUL, XUH, XUN) is connected to GND ?
... to ground. This characteristic is to accommodate similar parts by a competitor who places the Enable-Disable input on pin #2. All complementary output XU configurations (LVDS, LVPECL, & HCSL) have an option for Pin #2 E/D, instead of Pin #1. For other questions not ...
