TIDA-00073: The TSW1265EVM is an example design of a wideband RF to digital dual receiver solution capable of digitizing up to 125MHz of spectrum. The system provides a reference on how to use the ADS4249, LMH6521, LMK0480x, and a dual mixer to achieve this. This reference EVEM coupled with a capture card such as the TSW1400 can be used to capture and analyze narrow band and wideband signals. Instructions are provided on how to change the LO and IF frequencies for different application needs. The TIDA-00073 was implemented with hardware from the TSW1265EVM.
TIDA-00409: The TSW38J84 EVM reference design provides a platform to demonstrate a wideband dual transmit solution that incorporates an integrated LO. The reference design utilizes the 2.5 GSPS DAC38J84 device with the high performance modulators: TRF3722 (including integrated PLL/VCO) and TRF3705. The TRF3722 and TRF3705 can be combined to form a dual transmit solution with the TRF3722 generating the local oscillator (LO) for both modulators. The interface between the DAC38J84 and the modulators is discussed as well as measurements showing the combined performance of the DAC and modulators. The measurements illustrate the bandwidth performance, output third order intercept performance, harmonic distortion and sideband suppression performance.
TIDM-NFC-I2C-MODULE: This Near Field Communication (NFC) reference design provides a complete hardware and firmware example for an NFC Module with an I2C Communication interface. The firmware example demonstrates NFC Reader/Writer functionality by reading ISO15693, ISO14443A, ISO14443B, and Felica tags. Unlike some evaluation modules, this NFC module was designed specifically easy integration into existing applications. This reduces the resource demand on the developers while still supporting full functionality.
TIDA-00070: For applications where there are bit errors and resulting sample errors (also called sparkle codes, word errors, or code errors), the ability to measure the Error rates caused by these bit errors is important. This FPGA firmware based application note proposes a method to accurately measure these errors over an indefinite time and provides an example of how this measurement can be done using a simple FPGA platform. Code is available on request for the two examples described in the application note.
