AK8181B is a high speed, low skew, low output impedance and ultra-low power non-inverting clock driver. It is a multi-output buffered clock driver suitable for very low-jitter clock distribution applications. AK8181B provides an extremely fast rise and fall time equal to or better than 1ns, which makes it ideal for both clock and video clock distribution, as well as data formats that require minimal clock skew. The device also offers a low power consumption of just 55mW, and a very low output impedance of 30 Ohms.
The AK8181B is designed for clock and video clock distribution and multiplexing applications. The device has eight separate buffered clock outputs and each output can be configured to either be aninverting or non-inverting output. The device can operate at up to 200MHz, and it also has jitter attenuation up to 12ns. The device is also buffered in order to ensure that the outputs remain extremely low skew, even at very high frequencies.
The AK8181B can be used in many applications including datacommunication, computers and peripherals, digital video and telecom systems. The device is especially useful in multi-channel applications such as multiplexed digital video andaudio systems, where high data ratefrom peripheral devices are transferred to host devices over multiple channels simultaneously. This requires that the data clock has minimal skew, which is a challenge for many standardclock drivers. The AK8181B is ideal for such applications because of its low-skew and fast rise time attributes.
The working principle of the AK8181B is quite simple. The device has eight separate output clocks (six active, two to ground), each with individual current limiting resistors. In addition, each output has a separate enable line. When the enable lines are both active, the device will drive the clock on the corresponding output. The enable lines can also be used to output different clock signals on the sameoutput, thus allowing the device to act as a multiplexer. Additionally, the device may be used to drive different clock signals on different outputs.
The AK8181B is an extremely flexible and powerful device, and is capable of quite a lot of different applications. Its wide range of speeds, high-bandwidth and low-skew make it ideal for many applications including clock distribution, data communications, high-speed processor peripherals and multiplexed video systems. It also offers very low power consumption and output impedance, which make it a great choice for low-power applications.
All in all, the AK8181B is a very versatile device, with a wide range of applications in clock and video clock distribution, multiplexingand low-power applications. The device is easy to use and configure, and offers high-bandwidth, low jitter and low skew outputs. It is a great choice for applications that require robust clock performance.
