IC CHIP ST-114

The Intersil HSP45106 NCO and internal bit error rate tester generate either digital or analog FSK, BPSK or QPSK for loopback t

Key Features

1.Input:  Analog: -10 to -50 dBm, Digital: TTL data + clock2.Output:  Audio, I/Q, Clock + Data, Parallel TTL3.DSP:  TMS320C50 with JTAG connector4.Signal Generator:  FSK, BPSK, QPSK5.Size:  PC/AT with ISA bus

The ST-114 is a flexible PC/AT ISA bus evaluation platform for the Intersil HSP50214ProgrammableDownconverter.WithinamatterofminutesafterinstallationinaPC,theST-114 is up and running. The board simultaneously generates and tunes signals anywherefromdc to 20 MHz. Signal types include FM, FSK, BPSK and QPSK. Tuning anddemodulation are completely digital and allow nearly continuous bandwidth and data rateselection up to 1.2 MHz.The board is controlled through a Windows interface which allows full access to allHSP50214 registers, and provides controls and displays for FM, FSK, BPSK and QPSKsignal demodulation. To speed evaluation, the ST-114 includes a Intersil HI5703 10 Bit 40Msample/sec A/D converter, Texas Instruments TMS320C50 DSP processor, IntersilHSP45106 Numerically Controlled Oscillator, dual Intersil CA3338A high speed D/Aconverters and a 16 bit audio D/A converter.Forrapidprototypingdataandcontrolsignalscanbeaccessedinavarietyofways.Analogsignals are connected to the HI5703 A/D converter through a rear panel mounted SMAconnector. Alternatively, parallel TTL level digital signals can be input through a ribboncable connector on the board. Input samples are then processed by the HSP50214 andsupplied to  the TMS320C50 processor. The TMS320C50 implements carrier and datatrackingloopsandformatsthedataforoutputthroughthe18bitaudioD/Aconverterthatiscapable of driving standard multi-media speakers. The two CA3338A D/A convertersprovide wideband I/Q outputs.
