Notes:
1.
Permanent device damage may occur if absolute maximum ratings are exceeded. This is stress rating only and functional operation is not implied
at conditions other than those detailed in the operational sections of this data sheet. Exposure to absolute maximum rating conditions for extended
periods may affect device reliability.
2.
The data sheet limits are not guaranteed if the device is operated beyond the operating ratings.
3.
Measured with die attach pad soldered to PCB, JEDEC standard multi-layer board.
4.
The REFCLK
+ pin has a nominal 75 pull-down resistor connected to ground.
5.
The REFCLK
pin has a nominal 75 pull-down resistor connected to ground and a nominal 75 pull-up resistor connected to V
