Description:

Quad hcsl / lvds clock generator.

NB3N51054, Quad HCSL / LVDS Clock Generator

Pin # Pin Name Type 1 CLK2 HCSL or LVDS output Description Noninverted clock output.

(For LVDS levels see Figure 4) 2 CLK2 HCSL or LVDS Inverted clock output.

(For LVDS levels see Figure 4) output 3 GND Ground Power supply ground 0 V.

This pin provides GND return path for the device.

NB3N51054 3.3 V, Crystal to 100 MHz Quad HCSL/LVDS PCIe Clock Generator The NB3N51054 is a precision, low phase noise clock generator that supports PCI Express requirements.

The device accepts a 25 MHz fundamental mode parallel resonant crystal or a 25 MHz reference clock signal and generates four differential HCSL/LVDS outputs (See Figure 7 for LVDS interface) at 100 MHz clock frequency with maximum skew of 40 ps.

Through I2C interface, NB3N51054 provides selectable spread spectrum options of
