SCAN921821
Overview
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.
- 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 n > 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 required
- Internal PLL, no external PLL components required
- Single +3.3V power supply
- Low power: 260 mW (typ) per channel at 66 MHz with PRBS-15 pattern
