MK2014A  
Fast Ethernet Clock Source  
ICR O CLOC K  
Description  
Features  
• Packaged in 8 pin SOIC  
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.  
• 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  
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.  
• Zero ppm synthesis error in the output clocks  
• Full CMOS outputs with 25mA drive capability  
at TTL levels  
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.  
• 3.3V or 5V±10% supply voltage  
• Advanced, low power CMOS process  
• Insensitive to input clock duty cycle
