SCAN921821, Dual 18-Bit Serializer

The SCAN921821 is a dual channel 18-bit serializer featuring 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 embedded clock si
