DESCRIPTION

The UCC561 low-voltage differential (LVD) regulator

set is designed to provide the correct references

voltages and bias currents for LVD termination resistor

networks (475

9,

121

9,

and 475

9).

The device also

provides a 1.3-V output for 鈥渄iff sense鈥?signaling. With

the proper resistor network, the UCC561 solution meets

the common mode bias impedance, differential bias,

and termination impedance requirements of SPI--2

(Ultra2), SPI--3 (Ultra3/Ultra160) and SPI--4 (Ultra320).

The UCC561 is not intended for SPI--5 applications.

This device incorporates into a single monolith, two

sink/source reference voltage regulators, a 1.3-V

buffered output and protection features. The protection

features include thermal shutdown and active

current-limiting circuitry. The UCC561 is offered in

16-pin SOIC (DP) package.
