LVPECL Programmable Delay
with Fine Tune Control Precision EdgeВ®
The SY89296U is a programmable delay line that delays
the input signal using a digital control signal. The delay
can vary from 3.2ns to 14.8ns in 10ps increments. Further,
the delay may be varied continuously in about 40ps range
by setting the voltage at the FTUNE pin. In addition, the
input signal is LVPECL, uses either a 2.5V В±5% or 3.3V
В±10% power supply, and is guaranteed over the full
industrial temperature range (вЂ“40В°C to +85В°C).
The delay varies in discrete steps based on a control word.
The control word is 10-bits long and controls the delay in
10ps increments. The eleventh bit is D and is used to
simultaneously cascade the SY89296U for a larger delay
range. In addition, the input pins IN and /IN default to an
equivalent low state when left floating. Further, for
maximum flexibility, the control register interface accepts
CMOS or TTL level signals.
For applications that do not require an analog delay input,
