Analog Devices Inc. EVAL01-HMCAD1511

Overview

EVAL01-HMCAD1511 from Analog Devices is an evaluation board for the HMCAD1511 high-speed multi-mode 8-bit ADC, supporting single/dual/quad channel operation up to 1 GSPS. It enables rapid prototyping of high-bandwidth data acquisition systems with integrated crosspoint switching, 1×–50× digital gain, and LVDS/RSDS serial output - deployed in USB-powered oscilloscopes and satellite receivers.

For engineers reviewing the EVAL01-HMCAD1511 datasheet, EVAL01-HMCAD1511 pinout, EVAL01-HMCAD1511 application, or EVAL01-HMCAD1511 equivalent, this board provides full access to the HMCAD1511's configurable sampling modes (1000/500/250 MSPS), internal clock divider, fine/coarse gain control, and FPGA-compatible serial interface - critical for validating timing-critical ADC integration in test equipment and communications front-ends.

Technical Context

The EVAL01-HMCAD1511 implements a complete reference platform for the HMCAD1511 ADC, featuring on-board differential clock conditioning, 7×7 mm QFN-48 LP7D socketed footprint, and direct LVDS/RSDS signal routing to SMA connectors. It supports all three operational modes via SPI-configurable registers and includes dedicated power sequencing logic to meet the device's strict 0.5 µs sleep-to-active and 15 µs power-down recovery requirements.

Board-level design incorporates matched-length LVDS traces (<2.5 psrms inter-channel skew), calibrated 1.2 V common-mode output termination, and independent AVDD/DVDD/OVDD regulation aligned to the HMCAD1511's 1.8 V analog supply and 1.7–3.6 V CMOS logic voltage range - ensuring compliance with AC specs including 49.8 dB SNR (1× gain, 1000 MSPS) and 64 dBc SFDR (excluding interleaving spurs).

FAQ

What is the primary function of the EVAL01-HMCAD1511 evaluation board?

The EVAL01-HMCAD1511 evaluation board is designed exclusively to demonstrate and validate the HMCAD1511 8-bit high-speed ADC in real-world applications. It provides full electrical access to all I/Os, pre-characterized power delivery, clock conditioning circuitry, and SPI-based configuration - enabling engineers to verify sampling performance, gain calibration, channel crosstalk (≤70 dBc in quad mode), and LVDS timing compliance before system integration. The board does not contain additional processing or host interfaces beyond those required to operate the HMCAD1511.

Does the EVAL01-HMCAD1511 support all three operational modes of the HMCAD1511?

Yes, the EVAL01-HMCAD1511 fully supports single-channel (1000 MSPS), dual-channel (500 MSPS), and quad-channel (250 MSPS) modes of the HMCAD1511. Mode selection is implemented via SPI register writes (e.g., configuring sleep1_ch1, sleep2_ch<2:1>, or sleep4_ch<4:1>) and verified through the board's on-board jumpers and LED indicators. Each mode maintains full access to the integrated crosspoint switch, digital gain control (1×–50×), and internal offset correction - as specified in the HMCAD1511 datasheet revision v04.1015.

What clock sources are compatible with the EVAL01-HMCAD1511?

The EVAL01-HMCAD1511 accepts differential clock inputs via SMA connectors on CLKP/CLKN pins, supporting LVPECL, LVDS, CMOS, and sine wave formats per HMCAD1511 specifications. The board includes on-board AC coupling and biasing networks optimized for 1500 mVpp sine wave input and 50% duty cycle operation. It also integrates the HMCAD1511's internal programmable clock divider, allowing a single external clock source to drive all three sampling modes without external dividers.

How is digital output data routed and terminated on the EVAL01-HMCAD1511?

The EVAL01-HMCAD1511 routes all LVDS/RSDS outputs (DP1A/DN1A through DP4B/DN4B, LCLKP/LCLKN, FCLKP/FCLKN) directly to edge-mounted SMA connectors with controlled 100 Ω differential impedance and on-board 1.2 V common-mode termination. Output voltage levels are set to 350 mV (LVDS) or 150 mV (RSDS) as specified, and pipeline delays (32/64/128 clock cycles depending on mode) are preserved end-to-end. No level-shifting or buffering is applied - ensuring bit-accurate capture by external FPGAs.

Can the EVAL01-HMCAD1511 be used to evaluate HMCAD1510 or HMCAD1520 compatibility?

Yes - the EVAL01-HMCAD1511 is mechanically and electrically compatible with both HMCAD1510 and HMCAD1520 due to identical 7×7 mm QFN-48 LP7D packaging and pin-for-pin mapping. The board's firmware and layout accommodate HMCAD1510's functional subset (e.g., no quad-channel mode) and HMCAD1520's extended features (e.g., higher ENOB). However, full feature validation requires corresponding configuration register updates and verification against each device's respective datasheet - particularly for clock divider behavior and gain calibration algorithms.
