NB3N51044

3.3 V, Crystal to 100 MHz /

125 MHz Quad HCSL / LVDS

Clock Generator

The NB3N51044 is a precision, low phase noise clock generator that

supports PCI Express and sRIO clock requirements. The device

accepts a 25 MHz fundamental mode parallel resonant crystal or a

25 MHz single ended reference clock signal and generates four

differential HCSL/LVDS outputs (See Figure 10 for LVDS interface)

of 100 MHz or 125 MHz clock frequency based on frequency select

input F_SEL. NB3N51044 is configurable to bypass the PLL from

signal path using BYPASS, and provides the output frequency through

the divider network. All clock outputs can be individually enabled /

disabled through hardware input pins OE[3:0]. In addition, device can

be reset using Master Reset input pin MR_OE#.
