Exar introduces XR22404 and XR22417

October 7, 2016 – Exar Corporation, a supplier of analog mixed-signal products serving the industrial, infrastructure, automotive and audio video markets, today announced a family of USB 2.0 hubs.  The XR22404 and XR22417 are designed for applications where power consumption and board space are a concern such as docking stations, point-of-sale terminals, USB port expansion, test instrumentation, factory automation and other industrial applications.

The XR22404 is a USB 2.0 4-port hub controller that can be configured for downstream device charging and supports USB Battery Charging Specification 1.1 and 1.2. The XR22404 operates from either 3.3V or 5V supplies, allowing bus- or self-powered operation without an external LDO.  Available in a 4mm x 4mm, 24-pin QFN package, the XR22404 is a small USB 2.0 4-port hub controller. It is also available in a 28-pin SSOP for less space-constrained applications.

The XR22417 is a USB 2.0 7-port hub controller that utilizes Multiple Transaction Translators (MTT) for high bandwidth. Like the 4-port device in the family, the XR22417 benefits from design optimization that minimizes power and size to meet the challenging constraints facing connectivity and interface designers. The XR22417 is available in a 64-pin LQFP package as well as a smaller 48-pin LQFP.

The XR22404 and XR22417 are compatible with standard software drivers and include LED indicators to simplify implementation.  Both controllers attach to upstream ports at hi-speed (480Mbps) or full-speed (12Mbps).  The downstream PHYs support hi-speed, full-speed and low-speed (1.5Mbps) on each port.
