Wideband RF-to-Digital Complex Receiver-Feedback Signal Chain
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.

Equalization Optimization of a JESD204B Serial Link Reference Design
Employing equalization techniques is an effective way of compensating for channel loss in JESD204B high speed serial interfaces for data converters. This reference design features the ADC16DX370: a dual 16-bit: 370 MSPS analog-to-digital converter (ADC) that utilizes de-emphasis equalization to prepare the 7.4 Gbps serial data for transmission. Configuration allows a user to optimize the de-emphasis setting (DEM) and output voltage swing setting (VOD) of the output driver to inversely match the characteristics of the channel. Experiments demonstrate the reception of a clean data eye over 20” of FR-4 material at the full data rate.

Dual-Wideband RF-to-Digital Receiver Design
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.

700-2700 MHz Dual-Channel Receiver with 16-Bit ADC and 100 MHz IF Bandwidth Reference Design
The increasing demand on wireless networks to provide faster data links to customers has driven transceiver hardware to increasingly demanding performance with enough bandwidth to support the largest standardized multi-carrier frequency bands (with band aggregation in some cases) and enough receiver sensitivity and dynamic range to function in the presence of the strong blocking signals common in busy environments. This reference design describes a radio frequency (RF) receiver reference design with 16-bit sampler that achieves more than 100 MHz of bandwidth including a down-converting mixer: digital variable gain amplifier (DVGA): high speed pipelined analog-to-digital converter (ADC): local oscillator (LO) RF synthesizer and jitter-cleaning clock generator.
