FAQ

What is the primary function of the EKIT01-HMCAD1520 evaluation kit?

The EKIT01-HMCAD1520 evaluation kit is a fully assembled and tested hardware platform designed to demonstrate and validate the complete functionality of the HMCAD1520 high-speed multi-mode ADC. It enables engineers to evaluate all operating modes - including 1000 MSPS single-channel 8-bit, 640 MSPS dual-channel 12-bit, and 105 MSPS quad-channel 14-bit precision - with real-world FPGA interfacing, timing alignment, and power sequencing. The EKIT01-HMCAD1520 includes all necessary voltage regulation, clock conditioning, and LVDS signal routing to replicate production-grade signal integrity.

Does the EKIT01-HMCAD1520 support all HMCAD1520 output data formats?

Yes, the EKIT01-HMCAD1520 supports all HMCAD1520 serial LVDS output configurations: 12-bit, 14-bit, 16-bit, and dual-8-bit modes. Its onboard FPGA interface logic and configurable termination network allow direct connection to Xilinx Kintex/Virtex or Intel Stratix devices while maintaining compliance with LVDS electrical specifications (350 mV differential swing, 1.2 V common-mode). The EKIT01-HMCAD1520 firmware exposes register controls to select format, coding (offset binary or 2's complement), and frame clock ratio per HMCAD1520 datasheet Section 6.

How does the EKIT01-HMCAD1520 handle HMCAD1520 power sequencing and initialization?

The EKIT01-HMCAD1520 implements the exact power-on sequence mandated in the HMCAD1520 datasheet: synchronized 1.8 V AVDD/DVDD/OVDD ramp-up, followed by a RESETN pulse (>20 ns low) and PD pin assertion to ensure correct internal state initialization. It integrates dedicated sequencer logic and configurable delays to meet tSU = 15 µs (power-down to active) and TSLPCH = 0.5 µs (sleep channel to active) timing requirements. The EKIT01-HMCAD1520 also provides accessible test points for monitoring AVSS/DVSS domains and verifying analog/digital ground separation.

Can the EKIT01-HMCAD1520 be used to verify HMCAD1520's crosspoint switch and channel routing capabilities?

Yes, the EKIT01-HMCAD1520 includes four independent, impedance-matched differential analog input paths (IN1–IN4/IP1–IP4) with SMA connectors and on-board switching control. Its firmware allows dynamic reconfiguration of the HMCAD1520's integrated crosspoint switch via SPI to assign any input to any ADC channel in real time - validating use cases like diversity receiver channel hopping or time-interleaved sampling. Measured crosstalk (Xtlk,HS4) remains ≥70 dBc across all combinations, matching HMCAD1520 datasheet specifications.

Is the EKIT01-HMCAD1520 compatible with industry-standard FPGA development tools?

Yes, the EKIT01-HMCAD1520 ships with reference HDL code, PCIe-based PC host software, and GUI-driven configuration tools compatible with Xilinx Vivado and Intel Quartus Prime. It provides standard FMC-LPC connector pinout mapping to HMCAD1520 signals (LVDS data, clocks, SPI, power-good), enabling plug-and-play integration into larger system-level testbenches. All timing constraints - including TLATHSMS = 128 clock cycles pipeline delay in single-channel mode - are pre-characterized and included in the delivered constraint files for the EKIT01-HMCAD1520.
