DS92LV1021TMSA

Product Summary

The DS92LV1021TMSA transforms a 10-bit wide parallel CMOS/TTL data bus into a single high speed Bus LVDS serial data stream with embedded clock. The DS92LV1021TMSA receives the Bus LVDS serial data stream and transforms it back into a 10-bit wide parallel data bus and separates clock. The DS92LV1021TMSA may transmit data over heavily loaded backplanes or 10 meters of cable. The reduced cable, PCB trace count and connector size saves cost and makes PCB design layout easier. Clock-to-data and data-to-data skew are eliminated since one output will transmit both clock and all data bits serially. The powerdown pin is used to save power, by reducing supply current when either device is not in use. The Serializer has a synchronization mode that should be activated upon power-up of the device. The Deserializer will establish lock to this signal within 1024 cycles, and will flag Lock status. The embedded clock guarantees a transition on the bus every 12-bit cycle; eliminating transmission errors due to charged cable conditions. The DS92LV1021TMSA output pins may be TRI-STATE to achieve a high impedance state. The PLL can lock to frequencies between 16 MHz and 40 MHz.
