DOCSIS 3.0 plus upstream amplifier
8.3 Tx enable / Tx disable
The amplifier can be disabled or enabled by making TX_EN (pin 9) LOW or HIGH. A LOW
to HIGH Tx enable transition will activate new programed settings. If no new settings are
programmed the last programmed setting will be re-activated.
9. Limiting values
[1] All digital pins may not exceed V
CC
as the internal ESD circuit can be damaged. To prevent this it is recommended that control pins are
limited to a maximum of 5 mA.

Table 9. Limiting values
In accordance with the Absolute Maximum Rating System (IEC 60134).
Absolute Maximum Ratings are given as Limiting Values of stress conditions during operation, that must not be exceeded
under the worst probable conditions.
