General Description

The DS64BR401 is a quad lane bi-directional signal conditioning transceiver suitable for 6.0/3.0/1.5 Gbps SATA/SAS and other high-speed bus applications with data rates up to 6.4 Gbps. The device performs both receive equalization and transmit de-emphasis on each of its 8 channels to compensate for channel loss, allowing maximum flexibility of physical placement within a system. The receiver's continuous time linear equalizer (CTLE) provides a boost of up to +33 dB at 3 GHz and is capable of opening an input eye that is completely closed due to inter-symbol interference (ISI) induced by the interconnect medium. The transmitter features a programmable output de-emphasis driver and allows amplitude voltage levels to be selected from 600 mVp-p to 1200 mVp-p to suit multiple application scenarios. This Low Power Differential Signaling (LPDS) output driver is a power efficient implementation that maintains compatibility with AC coupled CML receiver. The programmable settings can be applied via pin settings or SMBus interface.

To enable seamless upgrade from SAS/SATA 3.0 Gbps to 6.0 Gbps data rates without compromising physical reach, DS64BR401 automatically detects the incoming data rate and selects the optimal de-emphasis pulse width. The device detects the out-of-band (OOB) idle and active signals of the SAS/SATA specification and passes through with minimum signal distortion.

With a typical power consumption of 200 mW/lane (100 mW/channel) at 6.4 Gbps, and control to turn-off unused channels, the DS64BR401 is part of National's PowerWise family of energy efficient devices.

Reliability Metrics

Part Number	Process	EFR Reject	EFR Sample Size	PPM	LTA Rejects	LTA Device Hours	FITS	MTTF (Hours)
DS64BR401SQ	BICMOS8B+	0	1152	0	0	743900	5	211083656
DS64BR401SQE	BICMOS8B+	0	1152	0	0	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.
