ADS6224IRGZ25 - Dual 12-Bit 105MSPS ADC LVDS | Texas Instruments
MPN: ADS6224IRGZ25 ✓ فعالADS6224IRGZ25 جائزہ
A pipelined ADC is a high-speed data-converter architecture that resolves each input sample through a chain of low-resolution stages with digital error correction, delivering high sample rates (tens to hundreds of MSPS) at moderate resolution (8-14 bits). Pipelined ADCs sit higher than successive-approximation (SAR) ADCs in the speed/resolution trade-off but lower than flash ADCs in raw analog bandwidth; they are members of the broader data-converter IC family, which also includes delta-sigma, SAR, and flash topologies. The ADS6224 belongs to TI's high-speed converter portfolio targeting communications, instrumentation, and defense imaging subsystems.
Key features include a maximum sample rate of 125 MSPS (the 105-MSPS grade shipped as IRGZ25 is pin-compatible with the 65/80/105/125 MSPS variants), simultaneous sample-and-hold for both channels, a 3.5 dB coarse gain option plus a 6 dB programmable fine gain, serialized LVDS output for low-EMI high-speed data transfer, and a 1.8 V analog / 3.3 V LVDS supply split. Total power dissipation is approximately 320 mW per channel at 105 MSPS, and the LVDS interface reduces board-routing complexity versus parallel CMOS outputs at >100 MSPS.
The ADS6224 uses a multi-stage pipeline with an internal sample-and-hold and supports both single-wire and dual-wire LVDS serialization to flex with board density and FPGA capture budgets. Its LVDS topology generates far less switching noise than parallel CMOS outputs, easing EMI compliance in dense multi-channel systems such as 4G base-station receivers and phased-array radar digitizers.
Typical applications include communications base-station receivers (multi-carrier GSM, LTE, WCDMA), multi-channel wireless infrastructure, medical imaging front-ends (ultrasound beamformers), defense and instrumentation (synthetic aperture radar, oscilloscope data acquisition), and dual-channel IF-sampling designs where both I and Q paths must be digitized concurrently with matched gain.
When designing with this device, decouple AVDD (1.8 V) and LVDDR (3.3 V) supplies independently with 1 µF + 100 nF ceramic capacitors placed within 5 mm of the supply pins, and provide a solid low-impedance ground plane under the exposed thermal pad. Route the LVDS output pairs with 100 Ω differential impedance and length-match within 150 ps to minimize inter-symbol jitter at the FPGA receiver.

عام استعمالات
ADS6224IRGZ25 کے لیے موزوں ہے 6 ایپلیکیشنs: Communications Base-Station Receiver, Medical Ultrasound Beamformer, Defense & Instrumentation Data Acquisition, Wireless Multi-Channel Infrastructure, Dual-Channel IF Sampling Module, Industrial Process Control Signal Acquisition.
Communications Base-Station Receiver
The ADS6224IRGZ25 is well-suited for multi-carrier GSM/LTE/WCDMA base-station receiver IF sampling where two matched 12-bit channels digitize I and Q paths. Its 105 MSPS per channel comfortably handles 20 MHz LTE carriers with adequate margin for adjacent-channel rejection, while the serialized LVDS output reduces parallel-routing congestion on the board. The 1.8 V analog supply and dual-channel integration also help shrink the BOM versus two single-channel ADCs with separate references.

Medical Ultrasound Beamformer
In mid-tier ultrasound beamformer front-ends, the ADS6224IRGZ25 digitizes two channels at up to 105 MSPS, supporting 16-to-32-element phased-array probe multiplexing schemes. Its 12-bit resolution suits B-mode imaging at 40-60 dB dynamic range, and the LVDS interface keeps board density manageable inside compact handle assemblies. Dual simultaneous sampling ensures the matched time delay across I/Q acquisition paths required for accurate beam steering.
تجویز کردہ
Defense & Instrumentation Data Acquisition
The ADS6224IRGZ25 serves in defense and test-and-measurement data-acquisition modules where dual matched channels digitize IF frequencies up to ~50 MHz with 12-bit amplitude resolution. The industrial -40 °C to +85 °C operating range ensures reliable operation in field-deployable chassis, and the serialized LVDS output minimizes radiated emissions — a key consideration for EMI-sensitive ISR and electronic-warfare subsystems.
تجویز کردہ
Wireless Multi-Channel Infrastructure
In multi-antenna wireless infrastructure such as small-cell and picocell radios, the ADS6224IRGZ25 provides dual 12-bit channel digitization at 105 MSPS for diversity/MIMO digitizing stages. Its compact 48-VQFN footprint and low ~320 mW per channel dissipation reduce board thermal load, while serialized LVDS output routing keeps PCB trace counts tractable in tight 4-layer radio modules serving 4G/5G small cells.
تجویز کردہ
Dual-Channel IF Sampling Module
The ADS6224IRGZ25 is purpose-built for dual-channel IF sampling where I and Q baseband or intermediate-frequency signals are digitized simultaneously with matched gain. Its simultaneous sample-and-hold eliminates timing skew between I/Q paths critical for vector signal analyzer accuracy, and the internal/external reference option lets designers tie the ADC to a shared system reference for absolute amplitude accuracy across multiple channels.
تجویز کردہ
Industrial Process Control Signal Acquisition
In high-speed industrial process control modules such as vibration monitoring on rotating machinery, the ADS6224IRGZ25 digitizes two accelerometer/IEPE channels at 105 MSPS for spectrum analysis and bearing-fault detection. Its industrial temperature range and serialized LVDS interface suit deployment near motors and pumps, while the dual-channel integration halves board real-estate versus discrete single-channel solutions in DIN-rail or PLC form factors.

ڈیزائن نوٹس
Decouple AVDD (1.8 V) and LVDDR (3.3 V) supplies independently with a 1 µF X7R ceramic in parallel with a 100 nF NP0/C0G ceramic placed within 5 mm of the respective supply pins. Route the analog and digital power planes as separate islands joined at a single point under the exposed thermal pad to prevent digital switching currents from coupling into the analog supply through the ground-return path.
Solder the exposed thermal pad (EP) directly to a continuous solid ground plane on the top PCB layer to provide a low-thermal-resistance path for internal dissipation (~320 mW per channel at 105 MSPS). Estimate: at +85 °C ambient and 700 mW total, junction temperature rise above ambient is approximately 30-40 °C with proper EP soldering — well within the 125 °C junction limit.
Route the LVDS output pairs (OUTAP/OUTAN, OUTBP/OUTBN, OUTCLK_P/OUTCLK_N) as 100 Ω differential microstrip with intra-pair length-matching within 150 ps (~25 mm at typical FR4 propagation) and keep the pair symmetric over a continuous reference plane. Keep LVDS traces away from the analog input pins (INP_A/INN_A, INP_B/INN_B) and the clock inputs (CLKP/CLKM) to avoid coupling noise back into the analog front-end.
Do not float the RESET or PDN pins — both must be driven actively (pull-up or driven high by the host) to ensure deterministic startup. The CLKP/CLKM differential clock must be low-jitter (<500 fs RMS) and AC-coupled with 0.1 µF caps for proper sampling; use a clock-cleaner/jitter-cleaner such as LMK04828 upstream of the ADC clock pin.
