Notes:
1. Permanent device damage may occur if ratings in the absolute maximum ratings section are exceeded. This is a stress rating only and
functional operation is not implied for conditions other than those detailed in the operational sections of this data sheet. Exposure to absolute
maximum ratings 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. Thermal performance assumes are of 4-layer PCB. Exposed pad must be soldered (or equivalent) to the device's most negative potential on
the PCB.
4. Excludes current of CML output stage. See “Detailed Description.”
5. Total device current with no output load.
6. Output levels are based on a 50
to VCC load impedance. If the load impedance is different, the output level will be changed. Amplifier is in
limiting mode. Measured at 155Mbps with 20mVpp input and PRBS-23 data pattern and 50
load.
