G261

The G261 LVD Regulator set is designed to provide the correct reference voltages and bias currents for LVD termination resistor networks (475Ω, 121Ω, and 475Ω). 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).

G261 contains two sink / source reference voltage regulators, a 1.3V buffered output and protection features. The protection features include thermal shutdown and active current limiting circuitry. The G261 is offered in 8 pin SOP and 16pin SOP.
