Synopsys Specialty IO and PHY

Synopsys Specialty IO library and PHY provide 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 IO library supports multiple voltages and a complete set of support cells (supply, corner spacers, diode breakers, terminators). Synopsys Specialty IOs meet critical power, performance, area (PPA), and reliability requirements for standards including LVDS, sLVDS, eMMC, I2C, I3C, and xSPI.


Synopsys Low Voltage Differential Signaling (LVDS) IO



Synopsys Low Voltage Differential Signaling (LVDS) IO library is a high-frequency interface that uses differential signals for data transmission. A few typical LVDS IO applications are in display monitors, printers, high-speed clock transfers, and high-speed SERDES. Synopsys LVDS IO library is used to build an LVDS-based interface for high-speed interconnect applications. This library is designed to optimize IO performance with a core voltage of 0.75 V and supports an IO 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 IO 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
