Using Calibration to Optimize Performance in Crucial Measurements
Today at the International Microwave Symposium (IMS), Texas Instruments Inc. (TI) introduced a family of 12-bit, 500- to 900-MSPS analog-to-digital converters (ADCs) that reduce board space by 80 percent while providing industry-leading signal-to-noise ratio (SNR) and spurious-free dynamic range (SFDR). The ADS5409 family provides best-in-class performance in a significantly smaller footprint and at the lowest power consumption to meet the size, power and performance needs of test and measurement equipment, wideband LTE and LTE-advanced communications base stations, millimeter wave backhaul (v-band and e-band), cable infrastructure return path and defense electronics.

Wideband LTE and LTE-advanced power amplifier linearization previously required large, expensive and high-power-consumption feedback ADCs for speeds greater than 500 MSPS. The ADS5409 family addresses these challenges by reducing IC size, cost and power, while providing the high performance needed to achieve transmit spectral mask requirements and improved power amplifier efficiency.
The pin-compatible ADS5409 family includes six 1- and 2-channel ADCs at a variety of speed grades and price points to meet system needs.
Pin-compatible, export-compliant family
Also new to the market, the complementary 12-bit ADS54T02 family includes three 1- and 2-channel, 500- to 750-MSPS dual-mode feedback and receiver ICs for time division duplex (TDD) base stations. The devices are pin-compatible with the ADS5409 family.
Evaluation modules (EVMs) for the ADS5409 and ADS54T02 families can be purchased today from the TI eStore for a suggested retail price of US$499. IBIS models are also available for verifying board signal integrity requirements.
For more extensive system-level evaluation, the TSW1400EVM data capture and pattern generation board provides a complete system to capture and evaluate data samples from high-speed ADC EVMs, and to generate and send desired test patterns to the high-speed digital-to-analog converter (DAC) EVMs. The complementary TSW1405EVM provides simple pattern capture with up to 64k sample depth.
For wideband digital pre-distortion (DPD) development, the TSW1266EVM DPD feedback reference design includes the 2-channel, 12-bit, 800-MSPS ADS5402 ADC, TI’s 2-channel LMH6521 digital variable gain amplifier (DVGA), LMK04808 dual-PLL clock jitter cleaner and a complex demodulator. The reference design can be configured for a variety of frequency plans by modifying the onboard filter components.
Support is available on the High Speed Data Converters Forum in the TI E2ETM Community, where engineers can ask questions and get answers from TI experts.
The 12-bit ADS5409 family includes the following devices, most which are available today in a 12-mm by 12-mm BGA package:
The 12-bit ADS54T02 family is also available today and includes the following devices in a 12-mm by 12-mm BGA package:
All prices quoted are for 1,000-unit quantities.
* The ADS5407 provides higher SNR and lower power consumption than the ADS5404.
