Electrical Characteristics
Transmission Characteristics
Transmit direction is Tip/Ring to XMT. Receive direction is IRCV/RCVN to Tip/Ring.
Table 8. ac Transmission Characteristics
1. Requires external components connected as shown in Figure 5. Transmission characteristics are specified assuming a 900
2. Transmission characteristics are specified assuming a 900
3. This parameter is not tested in production. It is guaranteed by design and device characterization.
