LTM2884 Series

Isolated USB Transceiver with Isolated Power

Analog Devices Inc.

The LTM® 2884 is a complete galvanically isolated USB 2.0 compatible μModule® (micromodule) transceiver. An upstream supply powers both sides of the interface through an integrated, isolated DC/DC converter.

Product Description

The LTM2884 is ideal for isolation in host, hub, bus splitter or peripheral device applications. It is compatible with USB 2.0 full speed (12Mbps) and low speed (1.5Mbps) operation. Automatic speed selection configures integrated pull-up resistors on the upstream port to match those sensed on the downstream device.
