A 0.9V/2.5V In-Line I/O Library in TSMC 55LP.
This SoundWire Digital I/O Library in TSMC 55nm LP is a silicon-proven interface solution for high-performance au- dio applications. Designed for 0.9V/2.5V operation, the Data, Clock, and Select I/Os, ensuring seamless integration with SoundWire-based systems. Engineered for reliability, the I/O cells meet 2kV HBM, 500V CDM, and 8kV system-level ESD protection (150pF, 330 Ohm direct contact to housing), with 18kV air discharge capability, offering exceptional robustness against electrostatic and environmental stress. This library is ideal for low-power, high-fidelity audio-designs, this I/O library deliver high signal integrity and compliance with industry standards.
