The MAX9174/MAX9175 are 670MHz, low-jitter, low-skew 1:2 splitters ideal for protection switching, loopback, and clock and signal distribution. The devices feature ultra-low 1.0ps(RMS)random jitter (max) that ensures reliable operation in high-speed links that are highly sensitive to timing errors.The MAX9174 has a fail-safe LVDS input and LVDS outputs. The MAX9175 has an anything differential input (CML/LVDS/LVPECL) and LVDS outputs. The outputs can be put into high impedance using the power-down inputs. The MAX9174 features a fail-safe circuit that drives the outputs high when the input is open, undriven and shorted, or undriven and terminated. The MAX9175 has a bias circuit that forces the outputs high when the input is open. The power-down inputs are compatible with standard LVTTL/LVCMOS logic. The power-down inputs tolerate undershoot of -1V and overshoot of VCC+ 1V. The MAX9174/MAX9175 are available in 10-pin µMAX and 10-lead thin QFN with exposed pad packages, and operate from a single +3.3V supply over the -40°C to +85°C temperature range.ApplicationsClock DistributionLoopbackProtection Switching

The MAX917–MAX920 nanopower comparators in space-saving SOT23 packages feature Beyond-the-Rails™ inputs and are guaranteed to operate down to +1.8V. The MAX917/MAX918 feature an on-board 1.245V ±1.5% reference and draw an ultra-low supply current of only 750nA, while the MAX919/MAX920 (without reference) require just 380nA of supply current. These features make the MAX917–MAX920 family of comparators ideal for all 2-cell battery applications, including monitoring/management.The unique design of the output stage limits supply-current surges while switching, virtually eliminating the supply glitches typical of many other comparators. This design also minimizes overall power consumption under dynamic conditions. The MAX917/MAX919 have a push-pull output stage that sinks and sources current. Large internal output drivers allow rail-to-rail output swing with loads up to 8mA. The MAX918/MAX920 have an open-drain output stage that makes them suitable for mixed-voltage system design.Applications2-Cell Battery Monitoring/ManagementMedical InstrumentsMobile CommunicationsNotebooks and PDAsSensing at Ground or Supply LineTelemetry and Remote SystemsThreshold Detectors/DiscriminatorsUltra-Low-Power Systems

The MAX9180 is a 400Mbps, low-voltage differential signaling (LVDS) repeater, which accepts a single LVDS input and duplicates the signal at a single LVDS output. Its low-jitter, low-noise performance makes it ideal for buffering LVDS signals sent over long distances or noisy environments, such as cables and backplanes.The MAX9180's tiny size makes it especially suitable for minimizing stub lengths in multidrop backplane applications. The SC70 package (half the size of a SOT23) allows the MAX9180 to be placed close to the connector, thereby minimizing stub lengths and reflections on the bus. The point-to-point connection between the MAX9180 output and the destination IC, such as an FPGA or ASIC, allows the destination IC to be located at greater distances from the bus connector.Ultra-low, 23psP-Padded deterministic jitter and 0.6psRMSadded random jitter ensure reliable communication in high-speed links that are highly sensitive to timing errors, especially those incorporating clock-and-data recovery, PLLs, serializers, or deserializers. The MAX9180's switching performance guarantees a 400Mbps data rate, but minimizes radiated noise by guaranteeing 0.5ns minimum output transition time.The MAX9180 has fail-safe circuitry that sets the output high for undriven open, short, or terminated inputs.The MAX9180 operates from a single 3.3V supply and consumes only 10mA over a -40°C to +85°C temperature range. Refer to the MAX9129 data sheet for a quad bus LVDS (BLVDS) driver, and to the MAX9181 data sheet for a low-jitter, low-noise 400Mbps LVPECL-to-LVDS level translator in an SC70 package.ApplicationsAdd/Drop MultiplexersCable RepeatersCell Phone Base StationsDigital Cross-ConnectsDSLAMsMultidrop BusesNetwork Routers and Switches
