SCAN921821 - Dual 18-Bit Serializer

Description

The SCAN921821 is a dual channel 18-bit serializer featuring signal conditioning, boundary SCAN, and atspeed BIST.

Each serializer block transforms an 18bit parallel LVCMOS/LVTTL data bus into a single Bus LVDS data stream with embedded clock.

Features

  • 1.
  • 2 15-66 MHz Dual 18:1 Serializer with 2.376 Gbps Total Throughput.
  • 8-level Selectable Pre-emphasis on Each Channel Drives Lossy Cables and Backplanes.
  • >15kV HBM ESD Protection on Bus LVDS I/O Pins.
  • Robust BLVDS Serial Data Transmission with Embedded Clock for Exceptional Noise Immunity and Low EMI.
  • Power Saving Control Pin for Each Channel.
  • IEEE 1149.1 "JTAG" Compliant.
  • At-Speed BIST - PRBS Generation.
  • No External Coding R.
