DS21448DK
3.3V E1/T1/J1 Line Interface Design Kit
Daughter Card
GENERAL DESCRIPTION
The DS21448DK is an easy-to-use evaluation board
for the DS21448 quad E1/T1/J1 LIU. It is intended to
be used as a daughter card with the DK101
motherboard or the DK2000 motherboard. A surface-
mounted DS21448 and careful layout of the analog
signal traces provide maximum signal integrity to
demonstrate the transmit and receive capabilities of
the DS21448. 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
interrupt status and receive-carrier loss for all four
ports. The evaluation board provides both RJ45 and
BNC connectors for the line-side transmit and receive
differential pairs on all four ports.
Each DS21448DK is shipped with a free DK101
motherboard. For complex applications, the DK2000
high-performance demo kit motherboard can be
purchased separately.
