Features SMPTE 292M, SMPTE 344M and SMPTE 259M compliant Data rates to 1.485 Gbps Dual differential inputs Dual 75 differential outputs Two selectable slew rates Adjustable output amplitude Single 3.3V supply operation Commercial temperature range: 0°C to +70°C Typical power consumption: 250mW in SD mode and 298mW in HD mode Description The LMH0202 Dual SMPTE 292M / 259M serial digital cable driver is a monolithic, high-speed cable driver designed for use in SMPTE 292M / 259M serial digital video and ITU-T G.703 serial digital data transmission applications. The LMH0202 drives 75 transmission lines (Belden 8281, Belden 1694A or equivalent) at data rates up to 1.485 Gbps. The LMH0202 provides two selectable slew rates for SMPTE 259M and SMPTE 292M compliance. The output voltage swing is adjustable via a single external resistor. The LMH0202 offers the flexibility to implement either dual differential inputs or a single differential input (externally routed via PCB) to dual differential outputs. The latter option provides an ideal solution for DVB-ASI applications where only the non-inverted outputs are typically used. The LMH0202 is powered from a single 3.3V supply. Power consumption is typically 250mW in SD mode and 298mW in HD mode. Applications SMPTE 292M, SMPTE 344M, and SMPTE 259M serial digital interfaces DVB-ASI applications Sonet/SDH and ATM interfaces Digital routers and switches Distribution amplifiers Buffer applications Video cameras

LMH0202MT	BICMOS8B+	0	3632	0	0	2762292	2	783807897
LMH0202MTX	BICMOS8B+	0	3632	0	0	2762292	2	783807897

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.
