DS21458DK
GENERAL DESCRIPTION
The DS21458DK is an easy-to-use evaluation board
for the DS21458 quad T1/E1/J1 transceiver. The
DS21458DK is intended to be used as a daughter
card with the DK101 motherboard or the DK2000
motherboard. The DS21458DK comes complete with
a DS21458 quad SCT, transformers, termination
resistors, configuration switches, line-protection
circuitry, network connectors, and motherboard
connectors. The DK101/DK2000 motherboard and
Dallas’ ChipView software give point-and-click
access to configuration and status registers from a
Windows ? -based PC. On-board LEDs indicate
receive loss-of-signal and interrupt status. An on-
board FPGA contains mux logic to connect framer
ports to one another or to the DK2000 in a variety of
configurations.
Each DS21458DK is shipped with a free DK101
motherboard. For complex applications, the DK2000
high-performance demo kit motherboard can be
purchased separately.
