SY604

Micrel-Synergy's SY604 is an ECL-compatible timing vernier (delay generator) whose time delay is programmed via an 8- bit code which is loaded concurrently with the circuit trigger. The SY604 is fabricated in Micrel-Synergy's proprietary ASSET™ bipolar process.

This device can be retriggered at speeds up to 125MHz, with a delay span as short as 4ns. At minimum span, the resolution is 4ns/255 = 15.7ps per step. The delay span is externally adjustable up to 40ns. The SY604 employs differential TRIGGER inputs, and produces a differential OUTPUT pulse; all other control signals are single-ended ECL. Edge delay is specified by an 8-bit input which is loaded into the device with the TRIGGER. The output pulse width will
typically be 3.5ns.

The SY604 is commonly used in Automatic Test Equipment to provide precise timing edge placement; it is also found inmany instrumentation and communications applications. Micrel-Synergy's circuit design techniques coupled with ASSET™ technology result in not only ultra-fast performance, but allow device operation at lower power dissipation than competing technologies. Outstanding reliability is achieved in volume production.
