Product Specification

Electronic Devices And Integrated Circuits 3V LVDS Single Amplifier IC Chip

General Description

  The DS90LV011A is a single LVDS driver device optimized for high data rate and low power applications. The DS90LV011A 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 in both a 5-lead small outline transistor package and a new LLP-8 package with a 3mm x 3mm body size. 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 DS90LV011A can be paired with its companion single line receiver, the DS90LV012A, or with any of National’s LVDS receivers, to provide a highspeed LVDS interface.

Recommended Operating Conditions

Switching Characteristics (Continued)

Note 1: “Absolute Maximum Ratings” are those values beyond which the safety of the device cannot be guaranteed. They are not meant to imply that the devices should be operated at these limits. The table of “Electrical Characteristics” specifies conditions of device operation.

Note 2: Current into device pins is defined as positive. 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 DS90LV011A 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. The parameter is guaranteed by design. The limit is based on the statistical analysis of the device over the PVT range by the transitions times (tTLH and tTHL).
