MK14223

3.3V Audio Codec Clock Source

ICROCLOCK

Description

Features

• Packaged in 8 pin SOIC

The MK14223 is the ideal way to generate clocks

for sound in portable computers. It provides clocks

for Analog Devices’ or Crystal Semiconductor’s

stereo codecs, and Yamaha’s OPL3 and OPL4

series. The MK14223 uses either a 14.31818 MHz

crystal, or a 14.31818 MHz bus clock input to

synthesize the clocks required to drive the codec.

It includes a Power Down pin to save power

without using external components. In an 8 pin

SOIC, the MK14223 can save component count,

board space, and cost over surface mount crystals,

and increase reliability by eliminating three

mechanical devices from the board.

• Input crystal or clock frequency of 14.318 MHz

• Output clock frequencies of 16.934 MHz,

24.576 MHz, and 33.868 MHz

• 25mA drive capability at TTL levels

• Advanced, low power CMOS process

• Low jitter ensures full 16 bit S/N ratio

• Insensitive to input clock duty cycle

• Power down for portable computers

• +3.3V or +5V operation

• Exact replacement for MK1422S

Additional Clocks or Features

If more than these three output clocks or features

such as output enable are needed, MicroClock can

provide a quick turn modification for your custom

requirements.

ICS/MicroClock offers many other parts with

stereo codec support. We invented sound clocks,

and have the widest product offering and greatest

production experience on these devices. The

MK14223 is the 3.3V version of the MK1422, and

also is pin compatible with our popular MK1420

when the 14.318MHz clock output is not used.
