Description Notes
J J8 FPGA / MSP JTAG Connector FPGA / MSP430 on SMT338-VP JTAG Chain. Only
routed down to SMT338-VP. Use for easy access
without having to remove the SMT381.
K U9 Fujitsu DAC DAC Requires heat-sink with air-flow cooling in a
system setup.
L TRANS2 M/A Com TP101 Transformer By default the SMT381 analog input is AC coupled
through a twisted pair balum transformer (differential to
single ended). It is possible to change this configuration
to DC coupled by taking out the transformer and
inserting some resistors on the board.
M TRANS1 M/A Com TP101 Transformer By default the SMT381 analog input is AC coupled
through a twisted pair balum transformer (differential to
single ended). It is possible to change this configuration
to DC coupled by taking out the transformer and
inserting some resistors on the board.
N VCO1 UMC 600 – 1200MHz VCO System Clock for the DAC. VCO Requires heat-sink
with air-flow cooling in a system setup.
O U31 Clock Synthesizer 50 –
950MHz
Test Clock for DAC. The range of this clock is wider
than the operating range of the DAC.
