MAX9180 19-2376 Rev 1 2/04 400Mbps, Low-Jitter, Low-Noise LVDS Repeater in an SC70 Package General Description Features The MAX9180 is a 400Mbps, low-voltage differential Tiny SC70 Package signaling (LVDS) repeater, which accepts a single Ultra-Low Jitter LVDS input and duplicates the signal at a single LVDS 23ps Added Deterministic Jitter output. Its low-jitter, low-noise performance makes it P-P 23 ideal for buffering LVDS signals sent over long dis- (2 - 1 PRBS) tances or noisy environments, such as cables and 0.6ps Added Random Jitter RMS backplanes. 0.5ns (min) Transition Time Minimizes Radiated The MAX9180s tiny size makes it especially suitable for Noise minimizing stub lengths in multidrop backplane appli- 400Mbps Guaranteed Data Rate cations. The SC70 package (half the size of a SOT23) allows the MAX9180 to be placed close to the connec- Fail-Safe Circuit Sets Output High for Undriven tor, thereby minimizing stub lengths and reflections on Inputs (Open, Terminated, or Shorted) the bus. The point-to-point connection between the Low 10mA Supply Current MAX9180 output and the destination IC, such as an FPGA or ASIC, allows the destination IC to be located Low 6mA Supply Current in Fail-Safe at greater distances from the bus connector. Conforms to ANSI/EIA/TIA-644 LVDS Standard Ultra-low, 23ps added deterministic jitter and P-P 0.6ps added random jitter ensure reliable commu- High-Impedance Inputs and Outputs in RMS nication in high-speed links that are highly sensitive to Power-Down Mode timing errors, especially those incorporating clock-and- data recovery, PLLs, serializers, or deserializers. The MAX9180s switching performance guarantees a 400Mbps data rate, but minimizes radiated noise by Ordering Information guaranteeing 0.5ns minimum output transition time. The MAX9180 has fail-safe circuitry that sets the output PIN - TO P PART TEMP RANGE high for undriven open, short, or terminated inputs. PAC K A G E M ARK The MAX9180 operates from a single 3.3V supply and MAX9180EXT-T -40C to +85C 6 SC70-6 ABH consumes only 10mA over a -40C to +85C tempera- ture 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.
