The Ultra High Speed Buffer Module will be shipped "ready to use",
with three NC7SZ125 chips soldered.

Description
Most I2S converter typical supply voltage equals 3.3V.
The I2S attenuators from ecdesigns i am using on my DAC module, are designed for 5V TTL levels only.
So we need the buffer between the output of these 3.3V devices and the input of my DAC module
for a proper work, without canceling the advantages of the I2S attenuators.
