bit code which is loaded concurrently with the circuit trigger.
The SY604 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 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.
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.
