STMicroelectronics STEVAL-CCH003V2

Overview

STEVAL-CCH003V2 from STMicroelectronics is an HDMI 2.0 interface evaluation kit built around the HDMI2C1-14HD dual-board configuration (main board + daughter board), supporting 4K/2K at 60 fps across -40 °C to +85 °C, with integrated ESD protection and RoHS compliance, used for HDMI transmitter-to-sink interoperability validation.

For engineers reviewing the STEVAL-CCH003V2 datasheet, STEVAL-CCH003V2 pinout, STEVAL-CCH003V2 application, or STEVAL-CCH003V2 equivalent, key considerations include HDMI2C1-14HD signal access points (HPD, SDA, SCL, CEC, TMDS lanes), power supply flexibility (+5 V DDC, +3.3 V CEC, VDD ASIC), and high-capacitance cable drive capability.

Technical Context

The kit implements a complete HDMI 2.0 physical layer interface using the HDMI2C1-14HD transceiver IC, providing full TMDS channel routing (clock + three data pairs), DDC/CEC bus isolation, HPD monitoring, and HEAC support. It enables functional verification of sink-side signal integrity, hot-plug detection timing, and robustness under high-load cable conditions.

Designed for lab-based HDMI compliance pre-validation, it exposes all critical control signals via headers (CN3, CN4, CN5) and supports jumper-configurable modes including standalone plug-and-play operation, power consumption profiling, and stress testing under varied VDD_IC and VDD_CEC voltage settings.

FAQ

Does STEVAL-CCH003V2 support HDMI 2.1 features such as eARC or VRR?

No. The kit is based on the HDMI2C1-14HD device, which implements HDMI 2.0 only. It supports up to 4K@60 Hz, TMDS signaling, DDC, CEC, and HPD-but not HDMI 2.1-specific protocols like eARC, VRR, or Dynamic HDR. Its design scope is strictly HDMI 2.0 compliance validation.

Can the main board operate without the daughter board?

Yes. The main board functions in standalone plug-and-play mode to verify basic HDMI source-to-sink connectivity. All essential TMDS, DDC, CEC, and HPD signals remain accessible via onboard connectors (CN1–CN5), and power rails (+5 V, +3.3 V, VDD_IC) are fully operational without daughter board attachment.

What is the role of the LD1117 regulator on the board?

The LD1117 low-dropout linear regulator provides a stable +3.3 V output for the CEC bus and associated logic, decoupled by C4 (100 nF) and C6 (1 µF). It ensures clean, low-noise power to the CEC interface circuitry independent of the main +5 V rail, improving noise immunity during CEC command transmission and reception.

How is ESD protection implemented on this evaluation kit?

ESD protection is fully integrated into the HDMI2C1-14HD IC itself-no external TVS diodes are used. The device meets IEC 61000-4-2 Level 4 (±15 kV air, ±8 kV contact) on all HDMI-facing pins (TMDS, HPD, CEC, SDA/SCL), verified per ST's characterization and reflected in the kit's RoHS-compliant, no-additional-protection design.
