SLIC Device Decoding
(For i, Channel = 1 or 2)
Unless otherwise noted, the test conditions are set up by the Le5711 device test circuit as illustrated in
a. Overload level is defined as THD = 1%.
b. Overload level is defined when THD = 1.5%.
Not tested in production. This parameter is guaranteed by characterization or correlation to other tests.
This parameter is tested at 1 kHz in production. Performance at other frequencies is guaranteed by characterization.
Group delay can be greatly reduced by using a Z
than 2 µs and increases 2WRL. The effect of group delay on linecard performance also may be compensated by synthesizing complex
impedance with the QLSLAC™ device.
Minimum current level guaranteed not to cause a false loop detect.
