Description

The PI90LV/LVB3487 and PI90LV/LVB9638 are differential line

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

into a low-voltage (350mV) differential output signal.

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.

The PI90LV/LVB3487 and PI90LV/LVB9638 and companion line

receivers (PI90LV/LVT3486 and PI90LV/LVT9637) provide new

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:

VOD1 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. tSKD2 is the Differential Channel-to-Channel Skew of any event on the same device.

7. 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 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.
