LVDS High-Speed Differential Line Drivers
Description
Features
• SignalingRates>400Mbps(200MHz)
• Single3.3VPowerSupplyDesign
• LowVoltageDifferentialSignalingwithTypicalOutput
Voltageof±350mVintothefollowing:
100-ohmload(PI90LVxxxx)
50-ohmload(PI90LVBxxxx)
• MaximumDifferentialSkewof 0.4ns
ThePI90LV/LVB3487andPI90LV/LVB9638aredifferentialline
drivers that use low-voltage differential signaling (LVDS) to sup-
port data rates in excess of 400 Mbps. These products are designed
for applications requiring high-speed, low-power consumption
and low noise generation.
A low voltage TTL/CMOS input level is translated by the device
intoalow-voltage(350mV)differentialoutputsignal.
• Typical Propagation Delay of 1.2ns
• MaximumPowerDissipation:25mW@200MHz/driver
Applications
Applications include point-to-point and multidrop baseband data
transmission over controlled impedance media of approximately
100-ohms. The transmission media can be printed circuit board
traces, backplanes, or cables.
ThePI90LV/LVB3487andPI90LV/LVB9638andcompanionline
receivers(PI90LV/LVT3486andPI90LV/LVT9637)providenew
alternatives to RS-232, PECL, and ECL devices for high-speed,
point-to-point interface applications.

Notes:
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.
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
OD1 and ∆VOD1.
3. All typicals are given for: VCC = +3.3V, TA = +25°C.
4. The PI90LV/LVB3487 and PI90LV/LVB9638 are current mode devices and only functions within datasheet specifications when a resistive
load is applied to the driver outputs typical range is 90 ohms to 110 ohms for PI90LVxxxx and 47 ohms to 55 ohms for PI90LVBxxxx.
5.
tSKD1, ItPHLD - tPLHDI is the magnitude difference in differential propagation delay time between the positive going edge and the negative
going edge of the same channel.
6.
7.
t
t
SKD2 is the Differential Channel-to-Channel Skew of any event on the same device.
SKD3, 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 VCC and with 5°C of each other within the operating temperature range.
8.
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
I Max - Min I differential propagation delay.
9. Generator waveform for all tests unless otherwise specified: f = 1 MHz, ZO = 50 ohms, tr ≤1ns, and tf ≤ 1ns.
10. Output short circuit current (IOS) is specified as magnitude only, minus sign indicates direction only.
11. CL includes probe and jig capacitance.
12. All input voltages are for one channel unless otherwise specified. Other inputs are set to GND.
13. fMAX generator input conditions: tR = tF <1ns, (0% to 100%), 50% duty cycle, 0V to 3V.
Output Criteria: duty cycle = 45%/55%, VOD >250mV, all channels switching.
