MAX3045BEWE+T

The MAX3045BEWE+T is a level-translator that provides a high-bandwidth half-duplex SDR/DDR signalling up to 1.76Gpbs on the differential I/O for 10G Ethernet, FibreChannel, SATA, and InfiniBand applications. This transceiver type device is used extensively in Interface – Drivers, Receivers, Transceivers applications. This article briefly describes the basic principles and applications of MAX3045BEWE+T.

Working Principle

The MAX3045BEWE+T uses a sliding rail voltage-based level-translator which enables the device to support both the 1.2V and 2.5V logic level across the bidirectional differential I/O. The device has on-chip ESD protection structure built-in. The MAX3045BEWE+T is capable of supporting SDR, CMD/DDR, and semi/full-duplex operation. In order to control the high-bandwidth signal, The MAX3045BEWE+T incorporates independent termination and pre-emphasis control for the transmit path, as well as independent receive equalization circuit. The MAX3045BEWE+T also provides on-chip adaptive high-frequency sinusoidal transmit clock and high-frequency pre-emphasis circuit for data recovery.
