DS90LV027A

LVDS Dual High Speed Differential Driver

General Description

Features

600 Mbps (300MHz) switching rates

The DS90LV027A is a dual LVDS driver device optimized for

high data rate and low power applications. The device is

designed to support data rates in excess of 600Mbps

(300MHz) utilizing Low Voltage Differential Signaling (LVDS)

technology. The DS90LV027A is a current mode driver al-

lowing power dissipation to remain low even at high fre-

quency. In addition, the short circuit fault current is also

minimized.

n 0.3 ns typical differential skew

n 0.7 ns maximum differential skew

n 1.5 ns maximum propagation delay

n 3.3V power supply design

360 mV differential signaling

n Low power dissipation (46 mW 3.3V static)

n Flow-through design simplifies PCB layout

n Interoperable with existing 5V LVDS devices

n Power Off Protection (outputs in high impedance)

n Conforms to TIA/EIA-644 Standard

n 8-Lead SOIC package saves space

n Industrial temperature operating range

(−40˚C to +85˚C)

The device is in a 8-lead small outline package. The

DS90LV027A has a flow-through design for easy PCB lay-

out. The differential driver outputs provides low EMI with its

typical low output swing of 360 mV. It is perfect for high

speed transfer of clock and data. The DS90LV027A can be

paired with its companion dual line receiver, the

DS90LV028A, or with any of National"s LVDS receivers, to

provide a high-speed point-to-point LVDS interface.

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 V

Note 3: All typicals are given for: V

= +3.3V and T = +25˚C.

Note 4: These parameters are guaranteed by design. The limits are based on statistical analysis of the device over PVT (process, voltage, temperature) ranges.

Note 5: C includes probe and fixture capacitance.
