Functional Description
The ASM2I9940L is a 1:18 low Voltage Clock distribution chip with 2.5V or 3.3V LVCMOS output capabilities. The device features the capability to select either a differential LVPECL or LVCMOS patible input. The 18 outputs are 2.5V or 3.3V LVCMOS patible and feature the drive strength to drive 50Ω series or parallel terminated transmission lines. With output-to-output skews of 150p S, the ASM2I9940L is ideal as a clock distribution chip for the most demanding of Synchronous systems. The 2.5V outputs also make the...
