PI3EQX8984ZLE

New Product Brief Product Databrief PI3EQX8908/8984 2.5Gbps/5.0Gbps/8.0Gbps 8-channel PCI Express ReDriver™ with Equalization & De-emphasis Pericom Semiconductor’s PI3EQX8908/8984 is a PCI Express Gen1/2/3 8-differential channels ReDriver™. Features ÎÎSupport up to 8Gbps serial link The device provides per channel programmable equalization, output swing, de-emphasis, and amplifier gain. ÎÎSupporting 8 channels in Flowthrough pin-out (54-pin PI3EQX8908) and 4 bi-directional lanes (72-pin PI3EQX8984) 2 The PI3EQX8908/8984 provides master / slave I C Control, to optimize performance over a variety of physical mediums by reducing Inter-symbol interference. ÎÎIndependent channel configuration of receiver equal- ization, output swing, de-emphasis, and amplifier gain PI3EQX8908/8984 supports eight 100-Ohm differential data I/O’s and extends the signals across other distant data pathways on the user’s platform. ÎÎPer Channel Activity Detector with selectable input term- ination between 50Ω to VDD and > 200KΩ ÎÎPer channel output termination detect on power-up with Pericom PI3EQX8908/8984 offers programmable transmit de-emphasis (up to 9 dB), transmit VOD (up to 1200 mVp-p) and receive equalization (up to 32.6 dB) to enable longer distance transmission in lossy copper cables (10m+), or backplanes (40”+) with multiple connectors. The receiver is capable of opening an input eye that is completely closed due to inter-symbol interference (ISI) introduced by the interconnect medium. selectable output termination between 100Ω differential and High Impedance ÎÎPin strap and I2C master / slave selectable device programming with external EEPROM ÎÎ4-bit selectable address bit for I2C ÎÎHot Plug Detect – allows host to reset if end point is removed (see note 1) The programmable settings can be applied easily via pins, software (I2C) or loaded via an external EEPROM. ÎÎSupply Voltage: 3.3V±10% ÎÎPackaging (Pb-free & Green): When operating in the EEPROM mode, the configuration information is automatically loaded on power up, which eliminates the need for an external microprocessor or software driver. àà 54-contact TQFN (10mm x 5.5mm, 0.5mm pitch) (PI3EQX8908) àà 72-contact TQFN (11mm x 5mm, 0.5mm pitch) (PI3EQX8984) - Backward Compatible to pinout of PI2EQX8864A Eye Diagram Before Channel Loss Before ReDriver After ReDriver Pericom ReDriver Host Channel Loss TX + RX + - Long input trace, cable, or connectors Long output trace, cable, or connectors Device Equalizer, De-emphasis, Swing, and Amplifier Gain End Point + + - - + + - - Output trace Input trace www.pericom.com | 1-408-232-9100 + RX + TX -
