Miniaturised MoBL-USB™ transceiver offers low-power operation

The TX3LP18 is a high-speed USB 2.0 transceiver available in a 20-pin Wafer Level Chip Scale Package (WLCSP) that measures only 2.2mm x 1.8mm. Cypress Semiconductor’s MoBL-USB™ TX3LP18 transceiver also offers low power consumption with a 0.5µA nominal sleep mode.

This combination can save board space and prolongs battery-life in a wide range of portable applications.

In addition to its small size, the device integrates multiple passive components in order to further reduce board-space usage and enable smaller end systems. The TX3LP18 removes the need for a dedicated 3.3V power supply with a wide input supply voltage range from 3.0V to 5.8V, and features an integrated Phase-Locked Loop (PLL) to supply USB clocking requirements without a dedicated crystal.

The TX3LP18 provides a high-speed physical layer interface that operates at the maximum allowable USB 2.0 bandwidth. Operation at various frequencies is supported, including the common 26MHz and 19.2MHz clock frequencies found in handsets.

A standard interface is provided that is USB 2.0 certified and compliant with the UTMI + Low Pin Interface (ULPI) specification.

 

FEATURES ULPI compliant/USB-2.0 certified for device operation Supports both USB 2.0 Hi-Speed (480Mbits/s) and Full-Speed (12Mbits/s) 8-bit Single Data Rate (SDR) ULPI data path Integrated regulator with 3.0V - 5.775V input 13MHz, 19.2MHz, 24MHz or 26MHz reference for integrated PLL Support for industrial temperature range: -40°C to 85°C
