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.
