ADS62P28IRGC25 Обзор
An analog-to-digital converter is a mixed-signal integrated circuit that converts continuous-time analog voltages into discrete digital codes at a specified sampling rate. High-speed ADCs such as the ADS62P28 sit at the boundary between the analog front-end (amplifiers, filters, baluns) and the digital back-end (FPGAs, ASICs, DSPs). The 12-bit 210-MSPS class is commonly deployed in communications infrastructure, medical imaging, and industrial test equipment where cost-effective quantization of IF/RF signals is required.
Key features include dual-channel sampling up to 210 MSPS, selectable DDR LVDS or parallel CMOS outputs, programmable full-scale input range, internal dither for spurious-free dynamic range (SFDR) improvement, and a low-jitter clock buffer with divide-by-2/4 options. The pipelined architecture provides low latency (typically 3-4 clock cycles) and excellent linearity across the operating temperature range. The 64-VQFN package with exposed thermal pad supports the 1.7 W typical power dissipation with standard PCB thermal design.
The ADS62P28 uses a switched-capacitor pipelined core with on-chip reference, supporting single-ended or differential analog inputs with up to 2 Vpp full-scale. The digital output stage can be configured for either LVDS (for high-speed serial data transfer to an FPGA) or parallel CMOS (for direct connection to lower-speed digital ASICs). Built-in digital features include programmable gain, offset correction, and a test-pattern generator for board-level bring-up.
Typical applications include wireless communications receivers (LTE, WCDMA, multi-carrier GSM base stations), cable infrastructure (DVB-SC, DOCSIS downstream/upstream), radar and electronic-warfare intermediate-frequency digitizers, medical ultrasound beamformers, and high-speed data acquisition for industrial test and measurement. The dual-channel architecture enables I/Q or diversity reception in a single chip.
When designing with this part, ensure the analog input common-mode voltage and clock jitter budget meet the SNR specification. Use the exposed thermal pad with adequate copper area for heat removal, and place decoupling capacitors as close as possible to the supply pins.

Типичное применение
ADS62P28IRGC25 подходит для 6 применениеs: LTE / WCDMA Base Station IF Sampling, Cable Infrastructure / DOCSIS Downstream, Medical Ultrasound Beamforming, Radar / Electronic Warfare IF Digitization, Test & Measurement Instrumentation, Industrial High-Speed Data Acquisition.
LTE / WCDMA Base Station IF Sampling
The ADS62P28IRGC25's dual 210-MSPS 12-bit conversion with 70 dBFS SNR and 85 dBc SFDR makes it well-suited for multi-carrier LTE and WCDMA base-station IF chains. Per TI's datasheet, two on-chip ADC cores handle independent I/Q or diversity paths simultaneously, eliminating the need for two discrete ADC ICs in a single-board radio. The DDR LVDS output streams up to 420 MSPS aggregate data into an FPGA or ASIC for downstream channelization. Compared with 14-bit alternatives, the 12-bit ADS62P28 provides adequate quantization for legacy 3G/4G receivers while consuming only 1.7 W typical - well within the thermal envelope of compact remote-radio-head designs.

Cable Infrastructure / DOCSIS Downstream
In cable-headend downstream digitizers, the ADS62P28IRGC25 samples IF outputs from QAM modulators at up to 210 MSPS, supporting DOCSIS 3.0/3.1 channel plans. According to the TI ADS62P28 datasheet, the dual-channel architecture enables capture of two independent downstream bands with a single chip, while the selectable DDR LVDS or parallel CMOS outputs simplify integration with cable-modem-termination-system (CMTS) ASICs. The internal reference and programmable 1-2 Vpp full-scale input range handle the wide dynamic range of aggregated QAM carriers without external level-shifting hardware.

Medical Ultrasound Beamforming
The ADS62P28IRGC25 is widely deployed in medical ultrasound front-end receivers, digitizing each transducer channel's echo return at rates up to 210 MSPS. Per TI's application information, the dual-channel pipelined architecture provides low-latency conversion essential for time-gain-compensation and beamforming pipelines, while the high SFDR (>85 dBc) preserves subtle tissue-contrast signals. The 64-VQFN package's small 9x9 mm footprint enables high channel density on ultrasound probe-interface boards, where dozens of channels must fit within a compact cable connector envelope.

Radar / Electronic Warfare IF Digitization
Defense and aerospace IF-sampling radar systems use the ADS62P28IRGC25 to digitize wideband intermediate-frequency signals from radar front-ends. According to TI's datasheet, the 450 MHz analog input bandwidth supports sub-sampling of IF bands up to 200 MHz with alias-protected Nyquist capture, while the dual channels enable simultaneous sum-and-difference channel digitization for monopulse radar. The industrial -40C to +85C temperature range accommodates the thermal environment of outdoor or vehicular radar installations.

Test & Measurement Instrumentation
High-end oscilloscopes, spectrum analyzers, and arbitrary-waveform-digitizers use the ADS62P28IRGC25 as a 12-bit digitizer for transient capture and signal analysis. Per TI's datasheet, the pipelined architecture's 3-4 clock-cycle latency is well-suited for trigger-and-capture workflows, and the selectable DDR LVDS output allows streaming to deep-memory FPGAs at full 210 MSPS. Combined with the part's 70 dBFS SNR, this ADC delivers an effective number of bits (ENOB) of approximately 11.3 at low input frequencies, adequate for general-purpose lab equipment.

Industrial High-Speed Data Acquisition
Industrial process control, vibration monitoring, and power-quality analysis deploy the ADS62P28IRGC25 for synchronized multi-channel sampling of sensor arrays. According to TI's datasheet, the dual-channel pipelined ADC with programmable full-scale input range (1-2 Vpp) accommodates a wide range of industrial sensors (accelerometers, current shunts, strain gauges) without external attenuators. The CMOS-parallel output mode simplifies connection to lower-cost industrial microcontrollers for embedded data loggers where the LVDS interface is not required.

Заметки по проектированию
Estimated: at 1.7 W typical dissipation in a 64-VQFN package, junction-to-ambient thermal resistance (theta_JA) is approximately 25 C/W on a 4-layer JEDEC test board. This yields a junction temperature rise of ~43C above ambient at full output rate, leaving margin to the 125C junction limit. For reliable operation at sustained 210 MSPS, solder the exposed thermal pad (pin 65 / DAP) directly to a copper pour of at least 1 square inch on the top layer, with thermal vias to internal ground planes.
The ADS62P28 requires two analog supplies (AVDD3V = 3.3 V for the analog front-end, AVDD1V8 = 1.8 V for the pipelined cores) and one digital driver supply (DRVDD = 1.8 V in LVDS mode). According to the TI datasheet, place 0.1 uF ceramic decoupling capacitors as close as possible to each supply pin, with a 10 uF bulk tantalum or ceramic capacitor on each supply rail to filter low-frequency noise. Star-ground the analog (AGND) and digital (DGND) returns at a single point under the exposed pad.
For clock integrity, drive CLKP/CLKN with a low-jitter differential source (typically <300 fs RMS jitter for full SNR). According to the TI ADS62P28 datasheet, the analog input bandwidth is 450 MHz; use a balanced, 100-ohm differential trace layout from the front-end balun/amplifier to the INA1P/N or INB1P/N pins. Keep the analog input traces short and symmetric to preserve common-mode rejection and minimize second-harmonic distortion.
The 64-VQFN package with exposed thermal pad requires proper PCB design for both electrical and thermal performance. Use a 9x9 mm land pattern with the central exposed pad exposed on the top layer (no solder mask) and an array of thermal vias (typically 0.3 mm diameter, 1 mm pitch) connecting to internal ground planes. Per TI's packaging guidelines, avoid routing signals beneath the package body and keep all high-speed LVDS traces length-matched within 1 mm to preserve DDR timing margins.
Common design pitfalls include: (1) leaving the exposed thermal pad unsoldered, leading to thermal overheating and SNR degradation; (2) failing to program the internal register map via SCLK/SDATA/SEN before operation - the device defaults to a safe state but must be configured for full performance; (3) using CMOS output mode when the downstream FPGA cannot accept DDR data rates - in this case, use LVDS mode with a 100-ohm termination at the receiver. Refer to TI's ADS62P28 datasheet register map for the correct power-up sequence.
