8EN31AK 32VFQFN - Block Diagram
説明
The 8EN31AK is a low skew, high performance 1-to-9 Differential-to-3.3V LVPECL Fanout Buffer and a member of the family of High Performance Clock Solutions from IDT. The 8EN31AK has two selectable clock inputs. The CLK, nCLK pair can accept most standard differential input levels. The PCLK, nPCLK pair can accept LVPECL, CML, or SSTL input levels. The clock enable is internally synchronized to eliminate runt pulses on the outputs during asynchronous assertion/deassertion of the clock enable pin. Guaranteed output skew and part-to-part skew characteristics make the 8EN31AK ideal for high performance workstation and server applications.
