SN65LVDS349 Datasheet | Texas Instruments

FEATURES - Meets or Exceeds the Requirements of ANSI TIA/EIA-644A Standard - Single-Channel Signaling Rates up to 560 Mbps - -4 V to 5 V mon-Mode Input Voltage Range - Flow-Through Architecture - SN65LVDS349 Provides a Wide mon- Mode Range Replacement for the SN65LVDS048A or the DS90LV048A APPLICATIONS - Logic Level Translator - Point-to-Point Baseband Data Transmission Over 100-Ω Media - ECL/PECL-to-LVTTL Conversion - Wireless Base Stations - Central Office or PABX Switches DESCRIPTION The SN65LVDS349 is a high-speed, quadruple differential receiver with a wide mon-mode input voltage range. This allows receipt of TIA/EIA-644 signals with up to 3-V of ground noise or a variety of differential and single-ended logic levels. The '349 is in a 16-pin package to match the industry-standard footprint of the DS90LV048. The '349 offers a flow-through architecture with all inputs on one side and outputs on the other to ease board layout and reduce crosstalk between receivers. The LVDS349 provides 3x the standard's minimum mon-mode noise voltage tolerance. The -4 V to 5 V mon-mode range allows usage in harsh operating environments or accepts LVPECL, PECL, LVECL, ECL, CMOS, and LVCMOS levels without level shifting circuitry. See the Application Information Section for more details on the ECL/PECL to LVDS interface.
