TYPICAL APPLICATIONS
Logic Analyzer Waveforms Show 2.05 s Throughput Rate (Input Voltage = 1.606V, Output Code = 0110 0100 0110 = 1606
NOTE: THE TMS320C50-40MHz HAS A LIMITED SERIAL PORT CLOCK SPEED OF 7.8MHz. TO ALLOW THE LTC1404 TO RUN AT
ITS MAXIMUM SPEED OF 9.6MHz, THE TMS320C50-57 OR TMS320C50-80MHz IS NEEDED
Hardware Interface to the TMS320C50’s TDM Serial Port (Frame Sync is Generated from TFSX)
