DS92LV042x 10-MHz to-75 MHz Channel Link II Serializer and Deserializer  
With LVDS Parallel Interface  
1 Features  
3 Description  
The DS92LV042x chipset translates a Channel Link  
LVDS video interface (4 LVDS Data + LVDS Clock)  
into a high-speed serialized interface over a single  
CML pair. The DS92LV042x enables applications  
currently using popular Channel Link or OpenLDI  
LVDS style devices to upgrade seamlessly to an  
embedded clock interface. This serial bus scheme  
reduces interconnect cost and eases design  
challenges. The parallel OpenLDI LVDS interface  
also reduces FPGA I/O pins, board trace count, and  
alleviates EMI issues when compared to traditional  
single-ended wide bus interfaces.

Emphasis  
The DS92LV042x chipset is programmable through  
an I2C interface as well as through pins. A built-in, at-  
speed BIST feature validates link integrity and may  
be used for system diagnostics. The DS92LV0421  
and DS92LV0422 can be used interchangeably with  
the DS92LV2421 or DS92LV2422. This allows  
designers the flexibility to connect to the host device  
and receiving devices with different interface types:  
LVDS or LVCMOS.
