SCAN921821  
Dual 18-Bit Serializer with Pre-emphasis, IEEE 1149.1  
(JTAG), and At-Speed BIST  
General Description  
Features  
n 15-66 MHz Dual 18:1 Serializer with 2.376 Gbps total  
throughput  
The SCAN921821 is a dual channel 18-bit serializer featur-  
ing signal conditioning, boundary SCAN, and at-speed BIST.  
Each serializer block transforms an 18-bit parallel LVCMOS/  
LVTTL data bus into a single Bus LVDS data stream with  
embedded clock. This single serial data stream with embed-  
ded clock simplifies PCB design and reduces PCB cost by  
narrowing data paths that in turn reduce PCB size and  
layers. The single serial data stream also reduces cable  
size, the number of connectors, and eliminates clock-to-data  
and data-to-data skew.  
n 8-level selectable pre-emphasis on each channel drives  
lossy cables and backplanes  
>
n
15kV HBM ESD protection on Bus LVDS I/O pins  
n Robust BLVDS serial data transmission with embedded  
clock for exceptional noise immunity and low EMI  
n Power saving control pin for each channel  
n IEEE 1149.1 "JTAG" Compliant  
n At-Speed BIST - PRBS generation  
n No external coding required  
n Internal PLL, no external PLL components required  
n Single +3.3V power supply  
n Low power: 260 mW (typ) per channel at 66 MHz with  
PRBS-15 pattern  
Each channel also has an 8-level selectable pre-emphasis  
feature that significantly extends performance over lossy  
interconnect. Each channel also has its own powerdown pin  
that saves power by reducing supply current when the chan-  
nel is not being used.  
The SCAN921821 also incorporates advanced testability  
features including IEEE 1149.1 and at-speed BIST PRBS  
pattern generation to facilitate verification of board and link  
integrity  
n Single 3.3 V supply  
n Fabricated with advanced CMOS process technology  
n Industrial −40 to +85˚C temperature range  
n Compact 100-ball FBGA package
