ETEK’s ET4559 SIM Card Interface Level Translator Achieves Qualcomm Platform Certification

2025/09/08

We are thrilled to announce that ETEK’s ET4559 SIM Card Interface Level Translator has successfully passed Qualcomm® platform certification, ensuring seamless integration with Qualcomm’s advanced chipset solutions. This milestone underscores our commitment to delivering high-performance, reliable components for next-generation mobile and IoT devices.

Why ET4559 Stands Out:

Robust Level Translation: Bridges 1.08V–1.98V host interfaces with 1.62V–3.6V SIM cards (CLK, RST, I/O).

EMI Filtering & ESD Protection: Integrated EMI suppression and 8kV ESD protection (IEC 61000-4-2 Level 4) safeguard against interference and electrostatic damage.

Compliance & Efficiency: Fully compliant with ETSI, ISO-7816, and IMT-2000 standards. Features automatic shutdown sequencing and zero-clamping to protect host controllers.

Compact Design: Ultra-small FOCSP9 package (1.06mm × 1.06mm) ideal for space-constrained applications.

Certified for Excellence

The Qualcomm certification validates the ET4559’s ability to deliver stable, high-speed communication (up to 10MHz) while meeting stringent power and signal integrity requirements. This ensures reliable performance in mission-critical applications such as:

5G smartphones and tablets

Wireless modems and IoT modules

SIM card terminals and secure payment systems
