557M-01LF Overview
There is a Tube package that contains it. 8-SOIC (0.154, 3.90mm Width) is included in the case. Clock program is recommended to mount using type Surface Mount. The device contains 1. In normaloperation, the maximum frequency is 100MHz. The operating temperature is varied over a range of 0°C~70°C. Clock program is possible for the component to supply a voltage of 3.135V~3.465V. Its primary purpose is PCI Express (PCIe). As the output, HCSL, LVDS should be used. Searching for information is made easier by using the ICS557-01 part number as the base number.
