Texas Instruments ADS62P43EVM

Overview

ADS62P43EVM from Texas Instruments is an evaluation module designed to characterize the ADS62P43 dual-channel, 14-bit, 65-MSPS analog-to-digital converter under real-world signal, clock, reference, and power supply conditions. It supports transformer-coupled or THS4509-amplified analog inputs, multiple clocking options (including external single-ended, crystal-filtered LVCMOS, and differential LVPECL), and configurable 3.3V/1.8V digital supply rails.

For engineers reviewing the ADS62P43EVM datasheet, ADS62P43EVM pinout, ADS62P43EVM application, or ADS62P43EVM equivalent, this page details its hardware configuration options, ADC interface modes (parallel vs. SPI), power supply topologies (LDO-only, switching+LDO, isolated), clock path selection (J19 direct, CDCE72010-based), and digital output routing (LVDS via J8 or CMOS via J1/J2).

Technical Context

The ADS62P43EVM implements a modular architecture with jumper-selectable signal paths: analog input can be routed through Mini-Circuits ADT4-1WT transformers or THS4509 amplifiers; clock input accepts either direct SMA injection at J19 or onboard generation via CDCE72010 PLL (factory-configured for ×4 division of VCXO) with crystal filtering or LVPECL output; digital outputs are LVDS by default on J8, with optional CMOS via U12/U13 buffers.

Power delivery supports three distinct configurations: Option 1 uses TPS79633/TPS79601 LDOs for low-noise 3.3V/1.8V supplies; Option 2 cascades TPS5420D (6–36V input) and TPS7A4501 for higher efficiency; Option 3 isolates AVDD/DVDD for precise current consumption measurement using center-post jumper connections on JP15/JP18.

FAQ

What is the primary function of the ADS62P43EVM?

The ADS62P43EVM is an evaluation module specifically built to assess the performance of the ADS62P43 dual-channel, 14-bit, 65-MSPS analog-to-digital converter. It provides configurable analog input paths (transformer or THS4509 amplifier), multiple clocking schemes (direct, crystal-filtered LVCMOS, or LVPECL), selectable power topologies, and flexible digital output routing (LVDS or CMOS). The ADS62P43EVM enables engineers to validate signal integrity, SNR, SFDR, and timing margins under realistic operating conditions before final system integration.

Does the ADS62P43EVM support both LVDS and CMOS digital outputs?

Yes, the ADS62P43EVM supports both interfaces. LVDS output is the default configuration, delivered via the 20-pin J8 connector with mandatory 100-Ωtermination at the receiver. CMOS output is available as an alternative: it requires installing buffer IC U12 for Channel A outputs (via header J1) or U13 for Channel B outputs (via header J2), replacing the default 0-Ωresistor networks that route signals to J8. This hardware-level reconfiguration ensures signal integrity matches the selected interface standard in the ADS62P43EVM design.

How is clocking configured on the ADS62P43EVM?

The ADS62P43EVM offers three clocking methods controlled by jumpers SJP4/SJP6/SJP7 and J14/J15. Default Clock Option 1 applies a clean external clock directly to SMA J19, converted to differential AC-coupled input via transformer. Option 2 uses the onboard CDCE72010 (pre-programmed for ÷4 division) with VCXO and crystal filter to generate 245.76 MHz LVCMOS clock on Y0. Option 3 routes differential LVPECL from Y1P/Y1N - though not recommended for SNR-critical use. All options maintain strict timing alignment between clock and analog input for coherent FFT analysis in the ADS62P43EVM setup.

What power supply options does the ADS62P43EVM provide?

The ADS62P43EVM supports three jumper-defined power configurations. Option 1 uses TPS79633/TPS79601 LDOs for ultra-low-noise 3.3V/1.8V supplies (5V input at J10). Option 2 employs a TPS5420D switching regulator + TPS7A4501 LDO cascade for higher efficiency across 6–36V input (J17), reducing thermal load while maintaining clean rails. Option 3 isolates AVDD and DVDD supplies via center-post jumper connections on JP15/JP18, enabling accurate per-rail current measurement - critical for power-sensitive designs evaluated with the ADS62P43EVM.

Can the ADS62P43EVM be used with other ADCs in the ADS62PXX family?

Yes, the ADS62P43EVM is explicitly designed as a common platform for multiple devices: ADS62P42/43/44/45/48/49, ADS62P22/23/24/25/28/29, and ADS62C15/17. Its jumper-based architecture accommodates differing supply requirements (e.g., 3.3V vs. 1.8V DVDD), input configurations, and register maps. The user guide confirms compatibility across all listed variants, and the ADS62P43EVM schematic includes provisions for device-specific decoupling and layout adaptations - making it a scalable evaluation tool within TI's high-speed ADC portfolio.
