PCIe 2.0 PHY in SMIC (40nm, 28nm)

Overview

Key Features

• Physical coding sublayer (PCS) block with PIPE interface
• Supports PCIe power management features, including L1 substate
• Power gating for lowest standby power
• Low active power using voltage mode TX with under drive supply options
• The multi-channel PHY macro with single clock and control core for higher density
• Supports both internal and external reference clock inputs
• PIPE bifurcation as well as PHY macro aggregation for x8 and x16 PHY configurations
• Multi-featured transmitter and receiver equalization
• Each lane in a multi-channel PHY macro contains its own pseudo random bit sequencer (PRBS) for internal and external loopbacks, used to verify TX and RX circuitry
• Each channel is fully controllable via the test access port (TAP) and core interface
• The PHY IP is capable of mapping the signal eye, and outputs the signal statistics via JTAG interface

Benefits
