Y1, Y2, Y3, Y4 (Pins 1, 5, 8, 11): These are the differential output pins of the device. They provide the LVDS (low-voltage differential signaling) signals to other components or devices. For each output, there is a corresponding inverted output (Y1' to Y4'), which can be used to generate the differential pair.
Y1', Y2', Y3', Y4' (Pins 2, 6, 9, 12): These are the inverted differential output pins. These output the inverse of the signals on Y1, Y2, Y3, and Y4, respectively. These are used in conjunction with the corresponding non-inverted pins to form differential pairs.
VEE (Pin 3): This is the negative supply voltage pin for the LVDS driver. It provides the necessary low-voltage differential signaling reference. Typical values for this pin range from -2.5V to -3.6V.
VCC (Pins 4, 10): These are the positive supply voltage pins. This provides the power to the chip. It typically operates at +3.3V or +5V depending on the system requirements.
GND (Pins 7, 16): These are the ground pins. They provide the reference ground for the chip to ensure proper signal operation.
EN (Pin 13): This is the enable pin. When this pin is driven high, it enables the differential output drivers. When it is low, the outputs are disabled.
IN1, IN2 (Pins 14, 15): These are the input pins for the device. They accept single-ended signals which are then converted into differential outputs on the Y1 to Y4 pins.
