Product details
Overview
ADS6242IRGZ25 from Texas Instruments is a dual-channel, 14-bit, 65 MSPS analog-to-digital converter with serial LVDS outputs, internal reference, and programmable coarse/fine gain. It features simultaneous sample-and-hold, 74.3 dBFS SINAD at 10 MHz input (0 dB gain), 93 dBc SFDR, and operates from 3.3-V analog/digital supplies in base-station IF receivers and medical imaging systems.
For engineers reviewing the ADS6242IRGZ25 datasheet, ADS6242IRGZ25 pinout, ADS6242IRGZ25 application, or ADS6242IRGZ25 equivalent, key selection factors include its 65 MSPS sampling rate, 48-pin QFN package, LVDS serialization interface (1-wire/2-wire selectable), industrial temperature range (–40°C to 85°C), and support for both internal/external reference modes.
Technical Context
The ADS6242IRGZ25 implements a dual 14-bit pipeline ADC architecture with simultaneous sampling per channel and integrated digital encoder/serializer. Its PLL derives bit/frame clocks from the input sampling clock, enabling serialized LVDS output at <1 Gbps using 2-wire DDR mode.
It supports flexible configuration via parallel pins (CFG1–CFG4, PDNA/PDNB, SEN) or SPI-compatible serial interface, with priority arbitration between them. Output data format (MSB/LSB first, 2's complement/offset binary), serialization ratio (14×/16×), and interface mode (1-wire SDR, 2-wire DDR/SDR) are all programmable.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 14-bit - guarantees no missing codes across full industrial temperature range. |
| Max Sampling Rate | 65 MSPS - defines maximum real-time bandwidth for undersampled RF/IF applications. |
| SINAD @ 10 MHz | 74.3 dBFS (0 dB gain) - determines effective dynamic range for low-frequency signal capture. |
| SFDR @ 10 MHz | 93 dBc (0 dB gain) - sets spurious-free resolution limit for high-fidelity digitization. |
| Power per Channel | 315 mW - enables thermal management in dense multi-ADC systems without external decoupling. |
| Analog Input BW | 500 MHz - supports direct sampling of IF signals up to ~250 MHz (Nyquist-limited). |
| Supply Voltage | 3.3 V ±10% (AVDD/LVDD) - simplifies power design with single LDO or DC/DC stage. |
Pinout & Package
ADS6242IRGZ25 is housed in a 48-pin QFN package (7 mm × 7 mm) with exposed thermal pad. Pin functions are validated per TI SLAS542B Rev. December 2013.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| INA_P / INA_M | Differential analog input, Channel A | Accepts 2-Vpp differential signal; common-mode voltage fixed at 1.5 V in internal ref mode. |
| INB_P / INB_M | Differential analog input, Channel B | Independent input path; supports diversity or I/Q sampling configurations. |
| CLKP / CLKM | Differential sampling clock input | Accepts LVPECL/LVDS/LVCMOS; amplitude down to 400 mVpp supported. |
| DCLKP / DCLKM | LVDS bit clock output | DDR clock derived by internal PLL; frequency = Fs × serialization ratio ÷ 2. |
| FCLKP / FCLKM | LVDS frame clock output | Indicates start of new 14-bit word per channel; synchronized to bit clock edges. |
| DA0_P / DA0_M DA1_P / DA1_M DB0_P / DB0_M DB1_P / DB1_M | LVDS serialized data outputs | 2-wire mode: DA0/DA1 carry Channel A MSB/LSB nibbles; DB0/DB1 carry Channel B. |
| PDNA / PDNB | Channel A/B power-down control | Hardware pin override: AVDD = channel powered down; 0 V = active conversion. |
| SEN / SCLK / SDATA | Serial interface enable/clock/data | Configures registers when SEN = low; supports 16-bit SPI-like write/read operations. |
| CFG1–CFG4 | Parallel configuration inputs | Set interface mode, serialization ratio, data format, and gain/reference without software. |
| REFP / REFM | Internal reference buffer outputs | Provide 2.0 V / 1.0 V reference; usable as external reference source if needed. |
| VCM | Common-mode output | 1.5 V output for biasing external analog circuitry or AC-coupled inputs. |
| AVDD / LVDD / AGND / LGND | Power and ground terminals | Separate analog/digital LVDS supplies reduce noise coupling; no external decoupling required. |
Key Features
| Feature | Design Value |
|---|---|
| Programmable coarse gain (0/3.5 dB) | Optimizes SFDR/SNR trade-off: +3.5 dB gain improves spurious performance at high input frequencies without degrading noise floor significantly. |
| 2-wire LVDS serialization | Halves serial data rate vs. 1-wire mode (e.g., 65 MSPS × 14-bit → 455 Mbps per channel), easing FPGA receiver timing closure and reducing PCB routing density. |
| Internal phase-locked loop (PLL) | Generates precise bit/frame clocks from input sampling clock-eliminates need for external clock synthesizer and reduces jitter-sensitive layout constraints. |
| Configurable output data format | Supports MSB/LSB-first and 2's complement/offset binary via CFG4 or register, enabling seamless integration with TI C6000 DSPs or Xilinx/Kintex FPGAs. |
| Parallel + serial configuration | Combines hardware pin-strapping (fast boot-time setup) with register-level fine-tuning (runtime reconfiguration), supporting both production robustness and system flexibility. |

|---|---|---|---|
| ADS6243IRGZT | Higher 80 MSPS sampling rate; 350 mW/channel power; 92 dBc SFDR @ 10 MHz. | Better suited for wider instantaneous bandwidth requirements (e.g., 40-MHz IF in 5G FR1). | Select when system requires >65 MSPS while retaining identical pinout, interface, and feature set. |
| ADS6222IRGZT | 12-bit resolution; 65 MSPS max; lower 220 mW/channel power; 81 dBc SFDR @ 10 MHz. | Targeted at cost-sensitive, lower-dynamic-range applications like broadband monitoring or basic spectrum analysis. | Choose for reduced BOM cost where 14-bit ENOB is not required and SNR >70 dBFS suffices. |
Compared with ADS6242IRGZ25, ADS6243IRGZT delivers higher speed at modest power increase, while ADS6222IRGZT trades resolution for lower cost and power-enabling tiered system design across performance bands without board redesign.

FAQ
What is the maximum sampling rate supported by ADS6242IRGZ25?
The ADS6242IRGZ25 supports a maximum sampling rate of 65 MSPS, as specified in the SLAS542B datasheet. This rate is guaranteed across the full industrial temperature range (–40°C to 85°C) with AVDD = LVDD = 3.3 V and proper clock conditioning. Exceeding this rate may result in degraded AC performance including reduced SFDR and increased aperture jitter.
Does ADS6242IRGZ25 require external decoupling capacitors on its power supplies?
No, ADS6242IRGZ25 does not require external decoupling capacitors on AVDD or LVDD supplies. The device integrates internal regulation and filtering optimized for its 3.3-V operation, as confirmed in the "Features" section and electrical specifications of the SLAS542B datasheet. This simplifies PCB layout and reduces bill-of-materials count.
Can ADS6242IRGZ25 operate with an external reference instead of the internal one?
Yes, ADS6242IRGZ25 supports external reference mode. When SEN pin is biased to 0 V or (3/8)LVDD, the device uses external reference applied to REFP/REFM pins. In this mode, full-scale input range becomes 2 Vpp (0 V) or 1.34 Vpp ((3/8)LVDD), and VCM remains at 1.5 V. Internal reference is disabled, allowing precision external references to define system accuracy.
What LVDS interface modes does ADS6242IRGZ25 support?
ADS6242IRGZ25 supports both 1-wire and 2-wire LVDS serialization, selectable via CFG1 pin or register. In 2-wire mode, each channel's 14-bit data is split across two differential pairs (e.g., DA0/DA1), halving the bit rate. In 1-wire mode, full 14-bit words are transmitted sequentially on a single pair, simplifying receiver design at lower sampling rates.
How is channel synchronization achieved in ADS6242IRGZ25?
ADS6242IRGZ25 achieves precise channel synchronization through a shared sampling clock (CLKP/CLKM) driving simultaneous sample-and-hold circuits for both channels. Inter-channel aperture variation is specified at ±80 ps over temperature, ensuring phase-coherent digitization critical for I/Q demodulation and beamforming. No external alignment circuitry is required.
