MK1491-06RTR Overview
There is a Tape & Reel (TR) package that contains it. 28-SSOP (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 49.152MHz. 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 3.15V~3.45V. Its primary purpose is AMD CPU. As the output, LVCMOS should be used. Searching for information is made easier by using the MK1491-06 part number as the base number.
