Features • DC - 125 MHz / 250 Mbps low jitter, low skew, low power operation • Independent Driver Enable pins • Outputs Conform to TIA/EIA-899 M-LVDS Standard • Controlled transition times minimize reflections • Inputs Conform to TIA/EIA-644-A LVDS Standard • 8 kV ESD on M-LVDS output pins protects adjoining components • Flow-through pinout simplifies PCB layout • Industrial operating temperature range (−40°C to +85°C) • Available in a space saving SOIC-16 package Description The DS91M125 is a 1:4 M-LVDS repeater designed for driving and distributing clock or data signals to up to four multipoint networks. M-LVDS (Multipoint LVDS) is a new family of bus interface devices based on LVDS technology specifically designed for multipoint and multidrop cable and backplane applications. It differs from standard LVDS in providing increased drive current to handle double terminations that are required in multi-point applications. Controlled transition times minimize reflections that are common in multipoint configurations due to unterminated stubs. A single DS91M125 channel is a 1:4 repeater that accepts M-LVDS/LVDS/CML/LVPECL signals and converts them to M-LVDS signal levels. Each output has an associated independent driver enable pin. The DS91M125 input conforms to the LVDS standard. The DS91M125 has a flow-through pinout for easy PCB layout. It provides a new alternative for high speed multipoint interface applications. It is packaged in a space saving SOIC-16 package. Applications • Multidrop / Multipoint clock and data distribution • High-Speed, Low Power, Short-Reach alternative to TIA/EIA-485/422 • Clock distribution in AdvancedTCA (ATCA) and MicroTCA (μTCA, uTCA) backplanes

Reliability Metrics

Part Number	Process	EFR Reject	EFR Sample Size	PPM	LTA Rejects	LTA Device Hours	FITS	MTTF (Hours)
DS91M125TMA	CMOS7	0	18406	0	0	1089000	4	309006723

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.
