General Description  
®
pins may be TRI-STATE  
to achieve a high impedance  
The DS92LV1021 transforms a 10-bit wide parallel CMOS/  
TTL data bus into a single high speed Bus LVDS serial data  
stream with embedded clock. The DS92LV1210 receives the  
Bus LVDS serial data stream and transforms it back into a  
10-bit wide parallel data bus and separates clock. The  
DS92LV1021 may transmit data over heavily loaded back-  
planes 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 elimi-  
nated 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 acti-  
vated 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  
state. The PLL can lock to frequencies between 16 MHz and  
40 MHz.  
Features  
n Guaranteed transition every data transfer cycle  
n Single differential pair eliminates multi-channel skew  
n Flow-through pinout for easy PCB layout  
n 400 Mbps serial Bus LVDS bandwidth (at 40 MHz clock)  
n 10-bit parallel interface for 1 byte data plus 2 control bits  
n Synchronization mode and LOCK indicator  
n Programmable edge trigger on clock  
n High impedance on receiver inputs when power is off  
n Bus LVDS serial output rated for 27load  
n Small 28-lead SSOP package-MSA
