Electrical Characteristics
(continued)
Transmission
Transmit direction is Tip/Ring to XMT. Receive direction is IRP/VRN to Tip/Ring.
Table 7. Transmission Characteristics
1. IEEEis a registered trademark of The Institute of Electrical and Electronics Engineers, Inc.
2. Assumes ideal external components.
3. This parameter is not tested in production. It is guaranteed by design and device characterization.
4. Transmission characteristics are specified assuming a 600
resistive termination; however, feedback using external components allows the
user to adjust the termination impedance from the intrinsic 600
of the feed resistors to most ITU-T recommended complex termination
impedances.
5. Measured with the L8575 SLIC connected per application diagram with ideal external components.
