Description
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 net-
work, 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).
This device contains two sink / source reference volt-
age 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.
