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.
