Features 12 to 85 MHz shift clock support 50% duty cycle on receiver output clock Low power consumption ±1V common-mode range (around +1.2V) Narrow bus reduces cable size and cost Up to 1.785 Gbps throughput Up to 223 Mbytes/sec bandwidth 345 mV (typ) swing LVDS devices for low EMI PLL requires no external components Rising edge data strobe Compatible with TIA/EIA-644 LVDS standard Low profile 48-lead TSSOP package Description The DS90CR218A receiver deserializes three input LVDS data streams into 21 bits of CMOS/TTL output data. When operating at the maximum input clock rate of 85 Mhz, the LVDS data is received at 595 Mbps per data channel for a total data throughput of 1.785 Gbit/sec (233 Mbytes/sec). The narrow bus and LVDS signalling of the DS90CR218A is an ideal means to solve EMI and cable size problems associated with wide, high-speed TTL interfaces.

Reliability Metrics

Part Number	Process	EFR Reject	EFR Sample Size	PPM	LTA Rejects	LTA Device Hours	FITS	MTTF (Hours)
DS90CR218AMTD	CMOS7	0	21301	0	0	1584000	3	449464325
DS90CR218AMTDX	CMOS7	0	21301	0	0	1584000	3	449464325

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.
