MK2014A
Fast Ethernet Clock Source
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.
Features
• Packaged in 8 pin SOIC
• Input crystal or clock frequency of 14.318 MHz
• Lowest jitter in the industry reliably clocks
sensitive Ethernet devices.
• Output clock frequencies of 20.00 MHz and
25.00 MHz
• Zero ppm synthesis error in the output clocks
• Full CMOS outputs with 25mA drive capability
at TTL levels
• 3.3V or 5V±10% supply voltage
• Advanced, low power CMOS process
• Insensitive to input clock duty cycle
