The DP83847 is designed for easy implementation of 10/100 Mb/s Ethernet home or office solutions. It interfaces to Twisted Pair media via an external transformer. This device interfaces directly to MAC devices through the IEEE 802.3u standard Media Independent Interface (MII) ensuring interoperability between products from different vendors. The DP83847 utilizes on chip Digital Signal Processing (DSP) technology and digital Phase Lock Loops (PLLs) for robust performance under all operating conditions, enhanced noise immunity, and lower external component count when compared to analog solutions.

Reliability Metrics

Part Number	Process	EFR Reject	EFR Sample Size	PPM	LTA Rejects	LTA Device Hours	FITS	MTTF (Hours)
DP83847ALQA56A	CMOS9	1	7912	127	0	1193000	3	338517007
DP83847ALQA56AX	CMOS9	1	7912	127	0	1193000	3	338517007

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.
