125MHz WRITE
PROGRAMMABLE
TIMING EDGE VERNIER
SY605
DESCRIPTION
FEATURES
Micrel-Synergy's SY605 is an ECL-compatible timing vernier
(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.
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 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.
The SY605 is commonly used in Automatic Test Equipment
to provide precise timing edge placement; it is also found in
many 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.
