The NB6L611 is a differential 1:2 clock or data fanout buffer. The differential inputs incorporate internal 50 W termination resistors that are accessed through the VTD pins and will accept LVPECL, CML, LVDS, LVCMOS or LVTTL logic levels. T h e V R E FA C r e f e r e n c e o u t p u t c a n b e u s e d t o r e b i a s capacitor-coupled differential or single-ended input signals. When used, decouple VREFAC with a 0.01 mF capacitor and limit current sourcing or sinking to 0.5 mA. When used, decouple VREFAC with a 0.01 mF capacitor and limit current sourcing or sinking to 0.5 mA. When not used, VREFAC output should be left open. The device is housed in a small 3x3 mm 16 pin QFN package. The NB6L611 is a member of the ECLinPS MAXTM family of high performance clock and data management products.
