(delay generator) whose time delay is programmed via an 8-
bit code which is loaded via an independent "WRITE" input.
The SY605 is fabricated in Micrel-Synergy's proprietary
ASSET™ bipolar process.
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 SY605 employs
differential TRIGGER and WRITE 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 WRITE signal. The output
pulse width will typically be 3.5ns.
to provide precise timing edge placement; it is also found in
many instrumentation and communications applications.
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.
