Synopsys Specialty I/O

Synopsys Specialty I/O library IP provides designers with the input/output operation, functionality and reliability required for SoCs targeting mobile, automotive, and high-performance computing (HPC) applications. Available in many foundries and process technologies from 3nm to 22nm, the specialty I/O library supports multiple voltages and a complete set of support cells (supply, corner spacers, diode breakers, terminators). Synopsys Specialty I/Os meet critical power, performance, area (PPA), and reliability requirements for standards including LVDS, sLVDS, eMMC, I2C and I3C.

Synopsys Low Voltage Differential Signaling (LVDS) I/O library is a high-frequency interface that uses differential signals for data transmission. A few typical LVDS I/O applications are in display monitors, printers, high-speed clock transfers, and high-speed SERDES. Synopsys LVDS I/O library is used to build an LVDS-based interface for high-speed interconnect applications. This library is designed to optimize I/O performance with a core voltage of 0.75 V and supports an I/O supply voltage of 1.2V/1.5 V. The library contains a transmitter, a receiver, and a bandgap reference circuit that is used to supply the current reference for the transmitter/receiver. The LVDS I/O library is compatible with the IEEE standard 1596.3-1996 and TIA/EIA - 644 -A. Key Features are:

  • Maximum operating speed: up to 3.4GBPS
  • Compatibility with TIA/EIA - 644-A for greater interoperability
  • Loop back option supported for both Pre/Post driver in LVDS TX
  • HBM 2KV, CDM 500V (up to 7A)
  • Silicon validated IP
  • Automotive G1/G2 supported, ASIL-B certified
  • Designed to support multiple metal stack options
  • Support for flip-chip & wirebond packaging

Synopsys Inter-Integrated Circuit (I2C) I/O library is used for two wire interfaces to connect low-speed devices like EEPROM, A/D, and D/A converters and microcontrollers on the same bus. It is designed for higher I/O voltage supply with support for low core voltage and includes fail-safe and fail-tolerance options. The following operating modes are supported:

  • Standard Mode: 100 kHz

  • Designed to support multiple metal stack options
  • Support for flip-chip & wirebond packaging

Synopsys I3C I/O library supports a simplified system of connecting and managing multiple sensors in a device. Multiple sensor secondary devices can be controlled by one I3C primary device at a time. It offers backward compatibility with I2C legacy devices, is designed for high I/O voltage domains and supports low-core voltage domains. The I3C incorporates the Schmitt-Trigger function, supports I2C Legacy Fast Mode and FM+ Mode, and includes HBM and CDM ESD protection. We provide an interoperable validated I3C I/O solution with our in-house Synopsys I3C controllers. The library supports independent power sequencing with the support of a power management cell from our base libraries. The Synopsys I3C I/O specifications align with the latest JEDEC standards and support:

  • Push-pull (12.5 MHz) and Open drain I3C modes (1MHz)
  • I2C Legacy Fast Mode (400KHz) and Fm+(1MHz) Mode
