Description
Features
E7765
1.3 GHz Quad
Pin Electronics Driver
The E7765 four channel, monolithic ATE pin electronics
solutions manufactured in a high-performance
complementary bipolar process.
The E7765 power consumption can be minimized to ac-
commodate the required performance and levels. The
E7765 has bias and other inputs that provide a means to
adjust performance versus power consumption. The
E7765 operates at data rates up to 1.3 GHz/2.6 Gbps.
• Four Fully Integrated, Three-Statable Drivers
• Wide Choice of Range, Performance vs. Power
• Differential Driver Mode
• Programmable Driver Rise, Fall Times
• –2V, +7V Driver Voltage Range
• Small, 80-Pin LQFP Package
The power supplies to the E7765 are specified over a wide
range to accommodate between –2V, +7V and –0.5V,
+4.2V output voltage ranges.
The E7765 driver is capable of generating 8V swings over
a –2 to +7V range. The driver minimum swing is 100 mV.
A differential driver mode configures pairs of adjacent driv-
ers on-chip to drive differential signals from a single data
input. The driver pairs are DOUT[0]:DOUT[1] and
DOUT[2]:DOUT[3]. The on-chip distribution of the driving
signal and the close matching of performance on-chip will
result in very low skew for differential output to output.
