General Description

The DS50EV401 is a low power, programmable equalizer specifically designed for PCI Express applications. The device provides 2 equalization settings to reduce inter-symbol interference (ISI) induced by a variety of interconnect media. One setting is optimized for PCIe Gen1 and Gen2 applications; the other is optimized for future Gen3 data rates. In all modes, the equalizer can operate, error free, with an input eye that is completely closed by interconnect ISI. The MODE, allows the user to select between equalization settings for 8Gbps operation or 2.5Gbps / 5.0Gbps operation.

The DS50EV401 enables PCI Express compatible link extension by supporting transmit electrical idle, and Beacon signal pass through on a per lane basis. Current-mode logic (CML) is used on both input and output ports, which provide constant 50 ohm single-ended impedance to AC ground. Differential signaling is implemented through out the entire signal path to minimize supply induced jitter. The DS50EV401 is available in a 7mm x 7mm 48-pin leadless LLP package, and is powered from a single power supply of either 3.3 or 2.5V.

Reliability Metrics

Part Number	Process	EFR Sample Size	LTA Device Hours	FITS	MTTF (Hours)
DS50EV401SQ	BICMOS8B+	1152	743900	5	211083656
DS50EV401SQE	BICMOS8B+	1152	743900	5	211083656
DS50EV401SQX	BICMOS8B+	1152	743900	5	211083656

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR. The Long Term Failure Rates were calculated at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress temperature of 150°C to an application temperature of 55°C.
