DS92LV090A数据手册集成电路（IC）的驱动器接收器收发器规格书PDF

描述 Description

The DS92LV090A is one in a series of Bus LVDS transceivers designed specifically for the high speed, low power proprietary backplane or cable interfaces. The device operates from a single 3.3V power supply and includes nine differential line drivers and nine receivers. To minimize bus loading, the driver outputs and receiver inputs are internally connected. The separate I/O of the logic side allows for loop back support. The device also features a flow through pin out which allows easy PCB routing for short stubs between its pins and the connector.
The driver translates 3V TTL levels (single-ended) to differential Bus LVDS (BLVDS) output levels. This allows for high speed operation, while consuming minimal power with reduced EMI. In addition, the differential signaling provides common mode noise rejection of ±1V.
The receiver threshold is less than ±100 mV over a ±1V common mode range and translates the differential Bus LVDS to standard (TTL/CMOS) levels. (SeeSection for more details.)
