Renesas HI5762EVAL2

Overview

HI5762EVAL2 from Intersil is an evaluation platform for the HI5762 dual 10-bit, 60MSPS analog-to-digital converter. It enables functional validation and performance characterization of the HI5762 in I/Q demodulation, high-speed data acquisition, and wireless baseband applications - supporting differential or single-ended analog inputs, internal 2.5V reference, and CMOS/TTL-compatible digital outputs at 6-cycle latency.

For engineers reviewing the HI5762EVAL2 datasheet, HI5762EVAL2 setup guide, HI5762EVAL2 application schematics, or HI5762EVAL2 compatibility with HI5762 ADC hardware integration, this platform provides verified signal integrity, clock distribution, power decoupling, and reference voltage conditioning to accelerate prototyping of dual-channel high-speed sampling systems.

Technical Context

The HI5762EVAL2 implements a complete signal chain around the HI5762 IC, including precision BNC analog input interfaces, buffered 2.5V internal reference routing (VROUT→VRIN), dedicated +5V analog/digital supply rails with 10µF/0.1µF decoupling per rail, and edge-aligned CMOS digital output bus termination. It supports both AC- and DC-coupled differential I/Q inputs via on-board biasing networks tied to the HI5762's IVDC/QVDC outputs.

Designed for direct connection to logic analyzers or FPGA capture interfaces, the board routes all 20 digital output bits (I/Q × 10-bit offset binary), CLK, and ground-referenced analog paths with controlled impedance and minimal stub length - preserving the HI5762's 250MHz full-power input bandwidth and <5psRMS aperture jitter performance.

FAQ

What is the primary function of the HI5762EVAL2?

The HI5762EVAL2 is a fully assembled and tested evaluation platform for the HI5762 dual 10-bit, 60MSPS analog-to-digital converter. It provides immediate hardware access to all critical signals - including differential I/Q analog inputs, 2.5V internal reference routing, sampling clock interface, and 20-bit CMOS digital outputs - enabling rapid validation of dynamic performance, timing alignment, and system-level integration without custom PCB design.

Does the HI5762EVAL2 require an external reference voltage?

No. The HI5762EVAL2 is configured to use the HI5762's internal 2.5V band-gap reference by default: VROUT is hardwired to VRIN via on-board traces and a 0.1µF stability capacitor, as specified in the HI5762 datasheet. An external reference may be substituted by modifying the VRIN connection point, but the default configuration requires no external reference source.

Can the HI5762EVAL2 support single-ended analog inputs?

Yes. While optimized for differential operation, the HI5762EVAL2 supports single-ended inputs via its IIN+ and QIN+ BNC connectors with appropriate external biasing. The board provides access to the HI5762's IVDC and QVDC 3.0V DC bias outputs, allowing users to establish correct common-mode voltage (0.25V–4.75V) for single-ended drive - consistent with the HI5762's specified input range and performance guarantees.

What power supplies are required to operate the HI5762EVAL2?

The HI5762EVAL2 requires a single +5V DC supply delivered through its barrel jack or screw-terminal header. Internally, it generates clean, separated analog (+5V AVCC1/2) and digital (+5V DVCC1/2/3) rails using low-noise regulation and layered decoupling (10µF tantalum + 0.1µF ceramic per supply pin), meeting the HI5762's strict noise and grounding requirements for 8.8 ENOB performance at 10MHz input.

Is the HI5762EVAL2 compatible with the HI5762/6IN and HI5762/6INZ packages?

Yes. The HI5762EVAL2 is designed exclusively for the HI5762 in the 44-lead MQFP package (Q44.10x10), which is used by both the HI5762/6IN and HI5762/6INZ variants. The board's footprint, thermal pad layout, and pin mapping match the official Intersil mechanical drawing Q44.10x10, ensuring mechanical and electrical compatibility across all temperature-range and Pb-free versions of the HI5762 IC.
