The receiver's • Advanced Configurable Signal Conditioning I/O continuous time linear equalizer (CTLE) provides high frequency boost that is programmable from 2.7 to 9.5 – Receive CTLE up to ~10 dB at 4 GHz dB at 4 GHz (8 Gbps) followed by a linear output – Linear Output Driver driver. The CTLE receiver is capable of opening an – Variable Output Voltage Range up to 1200 input eye that is completely closed due to inter mVp-p symbol interference (ISI) induced by interconnect medium such as board traces or twin axial-copper • Automatic Receiver Detect (Hot-Plug) cables. The programmable equalization maximizes • Ultra-Low Input-to-Output Latency: 80 ps (Typ) the flexibility of physical placement within the • Programmable via Pin Selection, EEPROM, or interconnect channel and improves overall channel SMBus Interface performance. • Single Supply Voltage: 2.5 V or 3.3 V When operating in PCIe applications, the • 4 kV HBM ESD Rating DS80PCI810 preserves transmit signal characteristics, thereby allowing the host controller • −40°C to 85°C Operating Temperature Range and the end point to negotiate transmit equalizer • Flow-Thru Layout in 10 mm x 5.5 mm 54-Pin coefficients. This transparency in the link training Leadless WQFN Package protocol facilitates system level interoperability and • Pin Compatible with DS80PCI800 minimizes latency. The programmable settings can be applied easily via 2 Applications pin control, software (SMBus or I2C), or direct loading from an external EEPROM. In EEPROM mode, the • PCI Express Gen-1, 2, and 3 configuration information is automatically loaded on • Other Proprietary High Speed Interfaces Up to 8 power up, thereby eliminating the need for an Gbps external microprocessor or software driver.
