16G PHY in TSMC (N7) for Automotive

Overview

Key Features

• Physical Coding Sublayer (PCS) block with PIPE interface
• Supports PCIe 6.0 (PAM-4), 5.0, 4.0, 3.1, 2.1, 1.1 encoding, backchannel initialization
• Supports x1, x2, x4, x8, and x16 hard macro configurations
• Lane margining at the receiver
• Optimized High performance analog front-end with adaptive continuous time linear equalizer (CTLE), decision feedback equalization (DFE) and feed forward equalization (FFE) for PCIe 5.0 and ADC/DSP based architecture for PCIe 6.0
• Continuous calibration and adaptation (CCA) for a robust performance across voltage and temperature variations
• Spread-spectrum clocking (SSC) and PCIe Separate Refclk Independent SSC (SSIS)
• Supports PCIe power management features, including L0p, L1 substate; power gating and power island; DFE bypass option and voltage mode Tx with under drive supply options
• The multi-channel PHY macro with single clock and control core for higher density with support for both internal and external reference clock inputs
• PIPE bifurcation as well as PHY macro aggregation for x1 to x16 PHY configurations
• Superior Rx jitter & cross talk tolerance reduces design constraints for a wider range of board layout designs
• Automated Test Equipment (ATE) test vectors for complete at-speed production testing
• Each PHY channel contains its own 7-, 9-, 11-, 15-, 16-, 23-, and 31-bit pseudo random bit sequencer (PRBS) for internal and external loopbacks
• Each channel is fully controllable via the integrated logic core as well as the test access port (TAP)
• Support for various form-factors

Benefits
