Wideband RF-to-Digital Complex Receiver-Feedback Signal Chain
TIDA-00074: This is a wideband complex-receiver reference design and evaluation platform that is ideally suited for use as a feedback receiver for transmitter digital predistortion. The EVM signal chain is ideal for high intermediate-frequency (IF) complex-feedback applications and contains a complex demodulator, TI’s LMH6521 dual-channel DVGA and ADS5402 12-bit 800-MSPS dual-channel ADC. By modifying the onboard filter components, the signal chain is configurable for a variety of frequency plans. The EVM also includes TI’s LMK04808 dual-PLL clock jitter cleaner and generator to provide an onboard low-noise clocking solution. The LMH6521 DVGA gain is controlled through the GUI or alternatively through the high speed connector with an FPGA.
Altera Arria V GX FPGA Power Solution Reference Design
PMP9449: The PMP9449 reference design provides all the power supply rails necessary to power Altera's Arria® V GX family of FPGAs. It utilizes a TPS38600 to monitor the input supply and provide power on sequencing. This design features low cost, small footprint discrete ICs and is powered from a single 5V input.
USB Type-A to USB TypeC SS (SuperSpeed) MUX with DFP Controller Reference Design
TIDA-00624: This addapter converts a USB standard host type-A port to Type-C DFP (downstream-facing port) with support for default, 1.5 A and 3.0A VBUS current levels. The TUSB2522 simplifies the design by integrating 2:1 USB 3.1 (up to 10 Gbps) mux with a DFP controller to monitor the Type-C configuration channel (CC) pins to determine plug orientation for mux selection and device attachment for controlling VCONN and VBUS power switches.
Three-Phase BLDC / PMSM Motor Drive with High-Performance Microcontrollers Reference Design
TIDM-RM46XDRV8301KIT: This TI design describes a motor control evaluation kit for spinning 3-phase brushless DC and brushless AC (BLAC) - often referred to as permanent magnet synchronous (PMSM) – motors with example of sensorless Field Oriented / Vector Control (FOC). The implementation leverages the DRV8301 gate-driver IC as well as the TPS65381 Power-Management IC. This reference design can be used as a high-performance, power-efficient, cost-effective platform to speed up development of PMSM control algorithms.
Power Reduction Using Dynamic Switching Reference Design
TIDA-00675: This design shows the power reduction benefits of dynamically switching a load on/off using a load switch. The design guide shows how frequency of switching, duty cycle, and the use of a discharge resistor can have an impact on power consumption.
Dual-Wideband RF-to-Digital Receiver Design
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-00278: This TI reference design is an automotive cluster telltale solution that includes a monolithic, medium-voltage, low-current power 12-bit shift register designed for use in systems that require relatively moderate load power, such as LEDs found in automotive clusters. This design is one part of an entire automotive cluster system solution optimized for the mid-end cluster market. The entire solution supports 4.5-40V system capabilities that can withstand cold crank, start stop, and load dump conditions.
1-GHz Bandwidth Dual Channel Transmitter up to 4-GHz Reference Design
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.
Synchronizing Multiple JESD204B ADCs for Emitter Position Location Reference Design
TIDA-00467: A common technique to estimate the position of emitters uses the amplitude and phase shift data of a signal derived from an array of spatially distributed sensors. For such systems, it is important to guarantee a deterministic phase relationship between the sensors to minimize errors in the actual measured data. This application design will discuss how multiple Analog to Digital Converters (ADCs) with a JESD204B interface can be synchronized so that the sampled data from the ADCs are phase aligned.
4 Port USB 3.0 Hub Reference Design
TIDA-00288: This verified reference design is a four-port USB 3.0 compliant hub. It provides simultaneous SuperSpeed and high-speed/full-speed connections on the upstream port and provides SuperSpeed, high-speed, full- speed, or low-speed connections on the downstream ports. The hub design provides power control for each downstream port and overcurrent protection.
JESD204B Link Latency Design Using a High Speed ADC
TIDA-00153: JESD204B links are the latest trend in data-converter digital interfaces. These links take advantage of high-speed serial-digital technology to offer many compelling benefits including improved channel densities. This reference design addresses one of the challenges of adopting the new interface: understanding and designing the link latency. An example achieves deterministic latency and determines the link latency of a system containing the Texas Instruments LM97937 ADC and Xilinx Kintex 7 FPGA.
