Features DC to 100+ MHz / 200+ Mbps low power, low EMI operation Optimal for ATCA, uTCA clock distribution networks Meets or exceeds TIA/EIA-899 M-LVDS Standard Wide Input Common Mode Voltage for Increased Noise Immunity DS91D176 has type 1 receiver input DS91C176 has type 2 receiver with fail-safe Industrial temperature range Space saving SOIC-8 package Description The DS91C176 and DS91D176 are 100 MHz single channel M-LVDS (Multipoint Low Voltage Differential Signaling) transceivers designed for applications that utilize multipoint networks (e.g. clock distribution in ATCA and uTCA based systems). M-LVDS is a new bus interface standard (TIA/EIA-899) optimized for multidrop networks. Controlled edge rates, tight input receiver thresholds and increased drive strength are sone of the key enhancments that make M-LVDS devices an ideal choice for distributing signals via multipoint networks. The DS91C176/DS91D176 are half-duplex transceivers that accept LVTTL/LVCMOS signals at the driver inputs and convert them to differential M-LVDS signals. The receiver inputs accept low voltage differential signals (LVDS, B-LVDS, M-LVDS, LV-PECL and CML) and convert them to 3V LVCMOS signals. The DS91D176 has a M-LVDS type 1 receiver input with no offset. The DS91C176 has an M-LVDS type 2 receiver which enable failsafe functionality.

Reliability Metrics

Part Number	Process	EFR Reject	EFR Sample Size	PPM	LTA Rejects	LTA Device Hours	FITS	MTTF (Hours)
DS91D176TMA	CMOS7	0	21301	0	0	1584000	3	449464325
DS91D176TMAX	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.
