Disclosed is a Negative Feed Back Methodology To Reduce Overshooting and Bounce For A TA Driver . In current design a slower slew rate driver is used to reduce overshooting and bounce. But a slower slew rate reduces a setup/hold time margin. This method is able to have higher slew rate and lower level noise of overshooting and bounce. ATA cable is a flat cable, has mutual coupling characteristic.It causes crosstalk noise at simultaneous and alternative switching. This driver has 4 kinds of slew rate to meet a several frequency transfer modes. This circuit controls dynamically the output slew rate.
