DS90C387/DS90CF388
The DS90C387A/CF388A chipset is electrically similar to the
DS90C387/CF388. The DS90C387/CF388 is intended for
improved support of longer cable drive. Cable drive is en-
hanced with a user selectable pre-emphasis feature that
provides additional output current during transitions to coun-
teract cable loading effects. Optional DC balancing on a
cycle-to-cycle basis, is also provided to reduce ISI (Inter-
Symbol Interference). With pre-emphasis and DC balancing,
a low distortion eye-pattern is provided at the receiver end of
the cable. A cable deskew capability has been added to
deskew long cables of pair-to-pair skew of up to +/−1 LVDS
data bit time (up to 80 MHz Clock Rate). These three en-
hancements allow cables 5+ meters in length to be driven
depending upon media and clock rate.
