MAX918 General Description

The MAX917MAX920 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 MAX917MAX920 family of comparators ideal for all 2-cell battery applications, including monitoring-management.

MAX9180 General Description

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-P added deterministic jitter and 0.6psRMS added random jitter ensure reliable communication in high-speed links that are highly sensitive to timing errors, especially those incorporating clock-anddata 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 to +85 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.
