PI3EQX5701ZDE

New Product Databrief PI3EQX5701 5.0Gbps, 1-lane, PCIe® 2.0 ReDriver™ with Digital Configuration Pericom Semiconductor’s PI3EQX5701 is a low power, high for the performance 5.0 Gbps signal ReDriver™ designed PCIe® 2.0 protocol. device provides programmable equalization, De-Emphasis, and input threshold controls to optimize performance Features • PCIe® 2.0 Compatible • Two 5.0Gbps • Adjustable Receiver Equalization • 100Ω • Pin with signal integrity of the signal before the ReDriver. A low-level • Input signal level detect and squelch for each channel input signal detection and output squelch function is provided for • Automatic Receiver Detect with digital enable/disable each channel. Each channel operates fully independently. When the • Electrical Idle fully supported channels are enabled (EN_x#=0) and operating, that channels’ input • Low Power (220mW) using 1.2V supply • Stand-by Mode – Power Down State • Single Supply Voltage: 1.2V or 3.3V • Packaging: 20-TQFN (4x4mm) over a variety of physical mediums by reducing Inter-Symbol Interference. PI3EQX5701 supports two 100Ω CML data I/O’s between the Protocol ASIC to a switch fabric, over cable, or to extend the signals across other distant data pathways on the user’s platform. integrated equalization circuitry provides signal level (on xI+/-) determines whether the output is active. If the input signal level of the channel falls below the active threshold level (Vth-) then the outputs are driven to the common mode voltage. In addition to signal conditioning, when both EN_x#=1, the device enters a low power standby mode. signal pairs CML I/O’s Output Emphasis Control PI3EQX5701 also includes a fully programmable receiver detect function. When the RxDet pin is pulled high, automatic receiver detection will be active. Redrivers with emphasis and equalization signal conditioning technology ensure the integrity of high-frequency PCIe 2.0 signals PCIe 2.0 signals must not only run reliably over varying lengths of by opening closed signal eyes to recover data and meet strict cable but also across multiple connectors and traces between the compliance testing requirements. Increased signal margin also transmitter and receiver. supports longer drive lengths over even low-quality cables. www.pericom.com | 1-408-435-0800
