P Btcor feir Intel Ethernet Connection C827 and XL827 Retimers extend the reach for 10GbE and 25GbE signals Key Features Overview Single port 100GbE to The Intel Ethernet Connection C827 and XL827 family of retimers extends 100GbE retimer the reach of the Ethernet signals. Retimers enable system designers to Four port 25GbE to optimize PCB material cost for longer channel routes on server and 25GbE retimer embedded designs. Single port 40GbE to 40GbE retimer These products offer three design options: Four port 10GbE to 1x 100GbE or 4x 25GbE retimer at industrial temperature operation 10GbE retimer 1x 100GbE or 4x 25GbE retimer at commercial temperature operation Supports independent 1x 40GbE or 4x 10GbE retimer at commercial temperature operation lane speeds CPRI Specification V7.0 By supporting a wide variety of IEEE and industry specifications for Ethernet, these retimers also enable maximum compatibility to Physical Forward Error Correction (FEC) Layer (PHY) media types. The retimers also support Common Public Radio Physical Media Dependent (PMD) training Interface (CPRI) to extend the reach between a base station and radio transceiver. Synchronous Ethernet (SyncE) Auto-negotiation Unlike a redriver, these retimers are capable of recovering and reclocking 2.6 W (typical) at 4x 25GbE the data. The retimers support Physical Media Dependent (PMD) control function for BASE-R training and Clause 73 Auto-Negotiation, and enable 14mm x 14mm FCBGA package Forward Error Correction (FEC) independent of the host controller. With the Intel Ethernet Connection C827 and XL827 family of retimers, the designer can expect a consistent link behavior compliant to IEEE specifications, and eliminate the requirement to manually tune the link on individual channels. duOperating Modes Platform Support Depending on data path requirements, the designer has the The Intel Ethernet Connection C827 and XL827 retimers efl xibility to operate the retimers in two operating modes: will be validated on future Intel Reference Platforms supporting system-on-a-chip products. Transparent mode retimes the data without decoding and re-encoding the PCS/FEC layers which lowers latency Intel Reference Platforms help customers implement through the retimer. In addition, CPRI data rates are solutions with high speed data paths. Please contact your supported in transparent mode. Intel Sales Representative for more information. Terminated mode decodes/encodes the PCS and FEC layers. Terminated mode can enable FEC on a data path that did not originally implement this Bit Error Rate improvement algorithm. In addition, each link of the retimer can be independent which allows for the mixing and matching of dieff rent PMDs. FEATURES DESCRIPTION Transparent mode Reduce latency with transparent mode by retiming data without decoding and re-encoding the PCS/FEC layers CPRI supported Terminated (protocol aware) mode PCS and FEC layers are terminated (decoded/encoded) enabling independent link segments Forward Error Correction (FEC) To significantly reduce Bit Error Rate (BER), the retimer can add forward error correction (FEC) in Terminated mode both RS-FEC (Reed Solomon) and KR-FEC are supported Autonomous Adaptive Receiver Equalization Automatic receive optimization yields the best performance on any link, eliminating the need for manual training IEEE 802.3 Auto-Negotiation and PMD Training For CR and KR PMDs, Auto-Negotiation selects the best operating speed and FEC mode, while PMD training optimizes transmitter equalization for the link partner and channel Independent port enabling and link speeds Each port can be configured and operated at different speeds and in different modes On-die thermal sensor Monitor on-die temperature program a threshold temperature to generate an interrupt INTERFACE DESCRIPTION Ethernet Interface Support 1GbE: 1000BASE-X/KX, SGMII 2.5GbE: 2500BASE-KX 10GbE: SFF-8431 SFI, 10GBASE-KR 25GbE: 25GBASE-KR/CR, 25GBASE-KR1/CR1, 25G-AUI, C2M 40GbE: XLAUI, XLPPI, 40GBASE-KR4/CR4 50GbE: 50GBASE-KR2/CR2 (Consortium) 100GbE: 100GBASE-KR4/CR4, CAUI-4 Common Public Radio Interface (CPRI) Specification V7.0 24330.24 Mb/s 12165.12 Mb/s 10137.6 Mb/s 9830.4 Mb/s 6144.0 Mb/s 4915.2 Mb/s 2457.6 Mb/s MECHANICAL AND THERMAL DESCRIPTION Lead-free technology and RoHS-compliant Complies with the European Union directive 2011/65/EU to reduce the use of hazardous materials Package 14mm x 14mm FCBGA Commercial temperature SKU Intel Ethernet Connection C827-AM will operate at 0C to 70C Industrial temperature SKU For extreme temperature environments, Intel Ethernet Connection C827-IM will operate at -40C to 105C PRODUCT NAME PRODUCT CODE Intel Ethernet Controller C827-AM EZC827AM Intel Ethernet Controller C827-IM EZC827IM Intel Ethernet Controller XL827-AM EZXL827AM
