Keywords:Semtech Corp.? E7765? quad-pin electronics driver?

Semtech Corp. has announced the E7765, touted to be the first off-the-shelf quad-pin electronics driver with the performance and differential signal capability required for testing next-generation, high-speed memory devices such as DDR III.

The E7765 supports both single-ended and full differential drive mode. In differential drive mode, precise complementary signals are created from adjacent channels on the chip. These signals are optimized to ensure less than 50ps of crossing point error for world-class timing accuracy.

The E7765 is capable of creating single-ended and differential signals with voltage swings as small as 100mV and up to 8V over a -2V to 7V common mode range. Each of the independent drivers is capable of generating signals with data rates up to 1.3GHz/2.6Gbps, putting the device in the top tier of performance for off-the-shelf pin electronics ICs.

Programmable rise and fall time adjustment allows for the driver output waveforms of the E7765 to be optimized for perfect symmetry. The extremely fast signal rise and fall times of this device allow it to sustain a wide data eye pattern in differential mode, enabling it to be used for at-speed testing of devices with high-speed differential inputs.
