Renesas Electronics 2-Channel Physical Layer Transceiver, 82P2282PFG

The Renesas Electronics transceiver is a highly featured single device solution for T1/E1/J1 trunks. Each link of the IDT82P2282 can be independently configured. The configuration is performed through an SPI or parallel microprocessor interface. In the receive path, the signals from the line side are coupled into the RTIPn and RRINGn pins and pass through an Impedance Terminator. In T1/J1 Mode, the recovered data and clock of each link can be configured in Super Frame (SF), Extended Super Frame (ESF), T1 Digital Multiplexer (DM) or Switch Line Carrier - 96 (SLC-96) formats. On the system side, if the device is in T1/J1 mode, the data stream of 1.544 Mbit/s can be converted to/from the data stream of 2.048 Mbit/s by software configuration. In the transmit path, the Transmit System Interface inputs the signals with various operating modes.
