I C R O C LOC K Description The MK2014A is the ideal way to generate clocks for Fast Ethernet cards or systems. It provides 20MHz and 25MHz clocks from an inexpensive 14.31818 MHz crystal or clock. In an 8 pin SOIC, the MK2014A can save component count, board space, and cost over surface mount crystals and oscillators, and increase reliability by eliminating mechanical devices from the board. The MK2014A is a functionally identical update of the MK2014 and should be used in all designs. The only change is in crystal load capacitance as stated on page 2. MicroClock offers many other clocks for computers and computer peripherals. Consult your MicroClock representative when you need to remove crystals and oscillators from your board.
