DS32EL0421, DS32ELX0421  
125 – 312.5 MHz Serializer with DDR LVDS Parallel LVDS  
Interface  
General Description  
The DS32EL0421/DS32ELX0421 is a 125 MHz to 312.5 MHz  
(DDR) serializer for high-speed serial transmission over FR-4  
printed circuit board backplanes, balanced cables, and optical  
fiber. This easy-to-use chipset integrates advanced signal  
and clock conditioning functions, with an FPGA friendly inter-  
face.  
Features  
5-bit LVDS parallel data interface  
Programmable transmit de-emphasis  
Configurable output levels (VOD  
)
Selectable DC-balanced encoder  
Selectable data scrambler  
Remote Sense for automatic detection and negotiation of  
link status  
The DS32EL0421/DS32ELX0421 serializes up to 5 parallel  
input LVDS channels to create a maximum data payload of  
3.125 Gbps. If the integrated DC-balance encoding is en-  
abled, the maximum data payload achievable is 2.5 Gbps.  
On chip LC VCOs  
Redundant serial output (ELX device only)  
The DS32EL0421/DS32ELX0421 serializers feature remote  
sense capability to automatically detect and negotiate link  
status with its companion DS32EL0124/DS32ELX0124 de-  
serializers without requiring an additional feedback path.  
Data valid signaling to assist with synchronization of  
multiple receivers  
Supports AC- and DC-coupled signaling  
Integrated CML and LVDS terminations  
Configurable PLL loop bandwidth  
Programmable output termination (50or 75Ω).  
Built-in test pattern generator  
The parallel LVDS interface reduces FPGA I/O pins, board  
trace count and alleviates EMI issues, when compared to tra-  
ditional single-ended wide bus interfaces.  
The DS32EL0421/DS32ELX0421 is programmable through  
a SMBus interface as well as through control pins.  
Loss of lock and error reporting  
Configurable via SMBus  
Target Applications  
48-pin LLP package with exposed DAP  
Imaging: Industrial, Medical Security, Printers  
Displays: LED walls, Commercial  
Key Specifications  
Video Transport  
1.25 to 3.125 Gbps serial data rate  
Communication Systems  
125 to 312.5 MHz DDR parallel clock  
Test and Measurement  
-40° to +85°C temperature range  
Industrial Bus  
>8 kV ESD (HBM) protection  
Low Intrinsic Jitter — 35ps at 3.125 Gbps
