SCAN921224 Datasheet | National Semiconductor

April 2001 .. SCAN921023/SCAN921224 20-66 MHz 10 Bit BLVDS Serializer and Deserializer with IEEE 1149.1 (JTAG) and at-speed BIST SCAN921023 and SCAN921224 20-66 MHz 10 Bit Bus LVDS Serializer and Deserializer with IEEE 1149.1 (JTAG) and at-speed BIST General Description The SCAN921023 transforms a 10-bit wide parallel LVCMOS/LVTTL data bus into a single high speed Bus LVDS serial data stream with embedded clock. The SCAN921224 receives the Bus LVDS serial data stream and transforms it back into a 10-bit wide parallel data bus and recovers parallel clock. Both devices are pliant with IEEE 1149.1 Standard Test Access Port and Boundary Scan Architecture with the...
