The SP322 is a programmable V.11 or V.35 transceiver IC. The SP322 contains three drivers and three receivers when selected in each mode. The selection is done by the V.11/V.35 select pin. The V.11 transceivers can typically operate at 10Mbps while adhering to the ITU V.11 specifications. The V.35 transceivers can operate up to 10Mbps while adhering to the I.
cable termination. Each SP322 driver contains a control pin which disables the output and places the output pins in a high impedance state. Each receiver also has a control pin which places the receiver outputs in a high impedance state. The enable pins will disconnect the internal termination network for whichever mode the SP322 is selected. For the receivers, the enable pin will place the input pins in a high impedance (approx. 15kΩ). This allows for convenient DTE-DCE configuration by connecting the driver outputs to the receiver inputs, thus allowing the enable pins to select the desired D.
