The G261 LVD Regulator set is designed to provide the correct reference voltages and bias currents for LVD termination resistor networks (475, 121, and 475). The device also provides a 1.3V output for DIFFSENSE signaling. With the proper resistor network, the G261 solution will meet the common mode impedance, differential mode impedance, differential bias voltage and common mode voltage requirements of SPI-2 (Ultra2), SPI-3 (Ultra 3/Ultra 160) and SPI-4 (Ultra 320).
