SCAN921025H, SCAN921226H
www.ti.com SNLS185C – OCTOBER 2004 – REVISED MAY 2013 SCAN921025H and SCAN921226H High Temperature 20-80 MHz 10 Bit Bus LVDS SerDes
with IEEE 1149.1 (JTAG) and at-speed BIST
Check for Samples: SCAN921025H, SCAN921226H FEATURES DESCRIPTION The SCAN921025H transforms a 10-bit wide parallel
LVCMOS/LVTTL data bus into a single high speed
Bus LVDS serial data stream with embedded clock.
The SCAN921226H 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 High Temperature Operation to 125В°C
IEEE 1149.1 (JTAG) Compliant and At-Speed
