Pin Descriptions (cont.)
PIN # PIN NAME TYPE DESCRIPTION
40 GND GND Ground pin.
41 DIF6 OUT Differential true clock output
42 DIF6# OUT Differential Complementary clock output
43 vOE6# IN
Active low input for enabling DIF pair 6. This pin has an internal pull-down.
1 =disable outputs, 0 = enable outputs
44 DIF7 OUT Differential true clock output
45 DIF7# OUT Differential Complementary clock output
46 vOE7# IN
Active low input for enabling DIF pair 7. This pin has an internal pull-down.
1 =disable outputs, 0 = enable outputs
47 VDDIO PWR Power supply for differential outputs
48 ^CKPWRGD_PD# IN
Input notifies device to sample latched inputs and start up on first high
assertion. Low enters Power Down Mode, subsequent high assertions exit
Power Down Mode. This pin has internal pull-up resistor.

Absolute Maximum Ratings
Stresses above the ratings listed below can cause permanent damage to the 9FGV0831. These ratings, which are standard
values for IDT commercially rated parts, are stress ratings only. Functional operation of the device at these or any other
conditions above those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum
rating conditions for extended periods can affect product reliability. Electrical parameters are guaranteed only over the
recommended operating temperature range.
