The DS2149DK/DS21349DK is a fully integrated
design kit for the DS2149 and the DS21349 T1/J1
line interface units (LIUs). It contains the necessary
circuitry to evaluate the device in all operation
modes, including running the device in hardware and
software mode.
Key Features
PLCC 28-pin socket for multiple part evaluation
Bantam and RJ48 connectors, transformers, and termination passives for LIU
Two separate and controllable transmit paths for TTIP and TRING for evaluating multiple transformers
Equipment-side connector for external data source/sink or external remote loopback
On-board T1 crystal oscillator
On-board 8051 microprocessor for software mode access
Connector accesses to CS, SCLK, SDI, and SDO for firmware development
Controllable 5V and 3.3V for VCC and IO pins to support the DS2149 and DS21349 LIUs
