MAXIM Integrated Products, represented by Arrow Electronics , has introduced the MAX9178 quad LVDS line driver with automatic termination detection.
The MAX9178 accepts LVTTL/LVCMOS inputs and translates them to LVDS output signals.
The outputs, upon detecting loss of termination, or sensing unterminated output during power-up, are driven high, thus eliminating cross talk. Upon termination, outputs become active.
The output signals comply with the requirements of the ANSI TIA/EIA-644 LVDS standards. All inputs tolerate Vcc + 1.0V overshoot and -1.0V undershoot.
The MAX9178 is suitable for applications requiring high data rates (up to 400Mbps), low power, and low noise. Applications include digital copiers, laser printers, base stations, telecom switches, and network switches and routers.
Two LVTTL/LVCMOS inputs, EN and EN-bar, set all four outputs to a high-impedance state and reduce power consumption to only 12.6mW (typ). The enablers are common to all four transmitters.
The MAX9178 operates from a single 3.3V ±10% supply and is specified for operation from -40°C to +85°C. The inputs and outputs meet IEC61000-4-2 Level 4 ESD specifications, with ±15kV for air discharge and ±8kV for contact discharge.
The MAX9178 is available in 16-pin TSSOP and QFN packages, and is a pin-compatible upgrade to National Semiconductor's DS90LV047A.
