DS92LV1021A数据手册集成电路（IC）的串行器解串器规格书PDF

描述 Description

The DS92LV1021A transforms a 10-bit wide parallel LVCMOS/LVTTL data bus into a single high speed Bus LVDS serial data stream with embedded clock. The DS92LV1021A can transmit data over backplanes or cable. The single differential pair data path makes PCB design easier. In addition, the reduced cable, PCB trace count, and connector size tremendously reduce cost. Since one output transmits both clock and data bits serially, it eliminates clock-to-data and data-to-data skew. The powerdown pin saves power by reducing supply current when the device is not being used. Upon power up of the Serializer, you can choose to activate synchronization mode or use one of TI’s Deserializers in the synchronization-to-random-data feature. By using the synchronization mode, the Deserializer will establish lock to a signal within specified lock times. In addition, the embedded clock specifies a transition on the bus every 12-bit cycle. This eliminates transmission errors due to charged cable conditions. Furthermore, you may put the DS92LV1021A output pins into TRI-STATE to achieve a high impedance state. The PLL can lock to frequencies between 16 MHz and 40 MHz.
