DS90LV011AQ Automotive LVDS Differential Driver General Description Features The DS90LV011AQ is an LVDS driver optimized for high data rate and low power applications. The DS90LV011AQ 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 designed to support data rates in excess of 400Mbps (200MHz) utilizing Low Voltage Differential Signaling (LVDS) technology. The device is offered in a 5-lead small outline transistor package. The LVDS outputs have been arranged for easy PCB layout. The differential driver outputs provide low EMI with its typical low output swing of 350 mV. The DS90LV011AQ can be paired with its companion single line receiver, the DS90LT012AQ, or with any of National's LVDS receivers, to provide a high-speed LVDS interface. ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ AECQ-100 Grade 3 Conforms to TIA/EIA-644-A Standard >400Mbps (200MHz) switching rates 700 ps (100 ps typical) maximum differential skew 1.5 ns maximum propagation delay Single 3.3V power supply ±350 mV differential signaling Power Off Protection (outputs in TRI-STATE) Pinout simplifies PCB layout Low power dissipation (23 mW @ 3.3V typical) SOT-23 5-lead package Pin compatible with SN65LVDS1 Connection Diagram 30063822 (Top View) Order Number DS90LV011AQMF See NS Package Number MF05A Functional Diagram 30063802 © 2008 National Semiconductor Corporation 300638 www.national.com DS90LV011AQ Automotive LVDS Differential Driver August 8, 2008 DS90LV011AQ Lead Temperature Range Soldering (4 sec.)

Current out of device pins is defined as negative. All voltages are referenced to ground except VOD. Note 3: All typicals are given for: VDD = +3.3V and TA = +25°C. Note 4: Output short circuit current (IOS) is specified as magnitude only, minus sign indicates direction only. Note 5: These parameters are guaranteed by design. The limits are based on statistical analysis of the device performance over PVT (process, voltage, temperature) ranges. Note 6: CL includes probe and fixture capacitance. Note 7: Generator waveform for all tests unless otherwise specified: f = 1 MHz, ZO = 50Ω, tr ≤ 1 ns, tf ≤ 1 ns (10%-90%). Note 8: The DS90LV011AQ is a current mode device and only function with datasheet specification when a resistive load is applied to the drivers outputs. Note 9: tSKD1, |tPHLD − tPLHD|, is the magnitude difference in differential propagation delay time between the positive going edge and the negative going edge of the same channel. Note 10: tSKD3, Differential Part to Part Skew, is defined as the difference between the minimum and maximum specified differential propagation delays. This specification applies to devices at the same VDD and within 5°C of each other within the operating temperature range. Note 11: tSKD4, part to part skew, is the differential channel to channel skew of any event between devices. This specification applies to devices over recommended operating temperature and voltage ranges, and across process distribution. tSKD4 is defined as |Max − Min| differential propagation delay. Note 12: fMAX generator input conditions: tr = tf < 1 ns (0% to 100%), 50% duty cycle, 0V to 3V. Output criteria: duty cycle = 45%/55%, VOD > 250mV.
