DS90LV017 LVDS Single High Speed Differential Driver General Description Features The DS90LV017 is a single LVDS driver device optimized for high data rate and low power applications. The DS90LV017 is a current mode driver allowing power dissipation to remain low even at high frequency. In addition, the short circuit fault current is also minimized. The device is in a 8-lead small Outline Package. The DS90LV017 has a flow-through design for easy PCB layout. The differential driver outputs provides low EMI with its low output swings typically 340 mV. n n n n n n n n Ultra Low Power Dissipation Operating Range above 155 Mbps Flow-through pinout simplifies PCB layout Conforms to TIA/EIA-644 Standard 8-Lead SOIC Package Saves Space VCM ± 1V center around 1.2V Low Differential Output Swing Typical 340 mV Power Off Protection (outputs in high impedance) Connection Diagram Dual-In-Line 01290001 Order Number DS90LV017M See NS Package Number M08A Functional Diagram 01290002 TRI-STATE ® is a registered trademark of National Semiconductor Corporation. © 2005 National Semiconductor Corporation DS012900 www.national.com DS90LV017 LVDS Single High Speed Differential Driver August 2005 DS90LV017 Absolute Maximum Ratings (Note 1) Lead Temperature Range If Military/Aerospace specified devices are required, please contact the National Semiconductor Sales Office/ Distributors for availability and specifications.
