Semtech Corporation EDGE629
The Edge629 is a monolithic timing delay and signal fanout solution manufactured in a high-performance bipolar process. It is also suitable for per pin deskew in Logic Testers. The Edge629 supports: • Minimum pulse width = 330 ps with Falling Edge Adjust disabled, 500 ps with Falling Edge Adjust enabled • Net usable delay span ≥ 4.0 ns • Falling Edge Adjust ± 250 ps • On Board DACs to generate 5 ps resolution With a maximum operating frequency of 1 GHz, the Edge629 is optimized for extremely high speed, high accuracy testers, particularly those aimed to test memory devices.| Part No. | EDGE629 |

● Fmax ≥ 1 GHz Independent Falling Edge Adjust Small Footprint (10 mm x 10 mm) Excellent Timing Accuracy Very Stable Timing Delays 5 ps Resolution ECL, CMOS Compatible Inputs In Automatic Test Equipment (ATE) applications, the Edge629 buffers, distributes, and aligns timing signals across multiple channels (typically found inside Memory Test Systems). The Edge629 solves several difficult problems associated with aligning multiple timing signals because it can:
● delay very narrow pulses over a long timing span
● adjust the falling edge independently from the overall propagation delay
● maintain extreme timing accuracy for very narrow (sub-ns) pulses
● maintain tight timing accuracy over changes in frequency, duty cycle, and pattern. Functional Block Diagram IN0 / IN0* ∆T– ∆T Coarse ∆T Fine OUT0 / OUT0* IN / IN* IN1/ IN1* ∆T– ∆T Coarse ∆T Fine OUT1 / OUT1* IN2 / IN2* ∆T– ∆T Coarse ∆T Fine OUT2 / OUT2*
