Am79C988A

PRELIMINARY

Notes:

1. Parameter is not tested.

2. Uses switching test load.

3. PDO pulses narrower than

tPWODO (min) will be rejected; PDO pulses wider than tPWODO (max) will turn internal PDO carrier

sense on.

4. PDO pulses narrower than

tPWKDO (min) will maintain internal PDO carrier sense on; PDO pulses longer than tPWKDO (max)

will turn internal PDO carrier sense off.

5. RXD pulses narrower than

tPWORD (min) will be rejected; RXD pulses longer than tPWORD (max) will turn internal RXD carrier

sense on.

6. RXD pulses narrower than

tPWKRD (min) will maintain internal RXD carrier sense; RXD pulses longer than tPWKRD (max) will

turn internal RXD carrier sense off.

7. Parameter tested functionally.
