Specifications of AM7943-2PC

• Lead Free Status / RoHS Status: Supplier Unconfirmed

Notes:
1. Unless otherwise noted, test conditions are V
2. a. Overload level is defined when THD = 1%.
3. Balance return signal is the signal generated at V
4. Not tested in production. This parameter is guaranteed by characterization or correlation to other tests.
5. This parameter is tested at 1 kHz with a termination impedance of 900
6. Tested with 0
7. Assumes the following Z
8. Group delay can be considerably reduced by using a Z
R
b. Overload level is defined when THD = 1.5%.

the group delay to less than 2 s. The effect of group delay on the linecard performance may be compensated for by using
the QSLAC™ or DSLAC™ device.
