Product Introduction

Overview

The SN65LVDS109DBT is a dual 4-port Low-Voltage Differential Signaling (LVDS) repeater manufactured by Texas Instruments. This device is designed to meet or exceed the requirements of the ANSI EIA/TIA-644 standard. It features two line receivers and eight line drivers, arranged in pairs from each bank, enabling precise timing alignment and high-speed data transmission. The SN65LVDS109DBT is packaged in a Thin Shrink Small-Outline Package (TSSOP) with 38 pins and operates over a temperature range of –40°C to 85°C.

  • Typical data signaling rates up to 400 Mbps or clock frequencies up to 400 MHz.
  • Outputs arranged in pairs from each bank with individual and global enable controls.
  • Low-Voltage Differential Signaling with typical output voltage of 350 mV and a 100-Ω load.
  • Electrically compatible with LVDS, PECL, LVPECL, LVTTL, LVCMOS, GTL, BTL, CTT, SSTL, or HSTL outputs with external termination networks.
  • Propagation delay times less than 4.5 ns and output skew less than 550 ps.
  • Driver outputs or receiver input equals high impedance when disabled or with VCC < 1.5 V.
  • Bus-pin ESD protection exceeds 12 kV.

Applications

The SN65LVDS109DBT is intended for point-to-point or point-to-multipoint (distributed simplex) baseband data transmission on controlled impedance media of approximately 100 Ω. This includes applications such as:

  • Printed-circuit board traces.
  • Backplanes.
  • Cables.
  • System clock and data distribution trees.
