3 Description

The TXV0106-Q1 is a 6-bit, dual-supply fixeddirection

low-skew, low jitter voltage translation

device. This device can be used for redriving, voltage

translation and power isolation when implementing

skew sensitive interface, such as RGMII between

Ethernet MAC and PHY. The Ax I/O pins and enable

pin (OE) are referenced to VCCA logic levels, and Bx

I/O pins are referenced to VCCB logic levels. This

device has improved channel-to-channel skew, duty

cycle distortion and symmetric rise or fall timing for

applications requiring strict timing conditions.

This device is fully specified for partial-power-down

applications using Ioff. The Ioff circuitry disables the

outputs, thus preventing damaging current backflow

through the device when it is powered down.

The VCC isolation feature is designed so that if either

VCC supply is at or near 0 V both ports will switch to

a high-impedance state. This feature enables power

isolation for communications across multiple MACs

and PHYs, and is beneficial in situations where MACs

and PHYs are powered up asynchronously preventing

current backflow between devices.

The TXV0106-Q1 transmits data in a fixed direction

from the A bus to the B bus. When OE is set to

High, both Ax and Bx pins will be forced into a highimpedance

state. See Device Functional Modes for a

summary of the operation of the control logic.
