www.ti.com SNLS148C – DECEMBER 2001 – REVISED APRIL 2013 SCAN921025 and SCAN921226 30-80 MHz 10 Bit Bus LVDS Serializer and Deserializer
with IEEE 1149.1 (JTAG) and at-speed BIST
Check for Samples: SCAN921025, SCAN921226 FEATURES DESCRIPTION The SCAN921025 transforms a 10-bit wide parallel
LVCMOS/LVTTL data bus into a single high speed
Bus LVDS serial data stream with embedded clock.
The SCAN921226 receives the Bus LVDS serial data
stream and transforms it back into a 10-bit wide
parallel data bus and recovers parallel clock. 1 2 IEEE 1149.1 (JTAG) Compliant and At-Speed
BIST Test Mode.
