Description
Channel 0 inverting and non-inverting differential inputs.
Channel 1 inverting and non-inverting differential inputs.
Channel 2 inverting and non-inverting differential inputs.
Channel 3 inverting and non-inverting differential inputs.
Channel 0 inverting and non-inverting differential outputs. (Note 1)
Channel 1 inverting and non-inverting differential outputs. (Note 1)
Channel 2 inverting and non-inverting differential outputs. (Note 1)
Channel 3 inverting and non-inverting differential outputs. (Note 1)
A logic low at PWDN activates the hardware power down mode.
Pre-emphasis Control Inputs (affects all Channels)
V_DD = 3.3V, ±5%
Ground reference for LVDS and CMOS circuitry.
No Connect
Note 1: The LVDS outputs do not support a multidrop (BLVDS) environment. The LVDS output characteristics of the DS90LV004 device have been optimized
for point-to-point backplane and cable applications.
