The SY89295U 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. In addition,
the input signal is LVPECL, uses either a 2.5V
±
5% or 3.3V
±
10% power supply, and is guaranteed over the full industrial
temperature range (–40
°
C to +85
°
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[10] and is
used to simultaneously cascade the SY89295U which allows
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 requires an analog delay input, see
the SY89296L which is a programmable delay chip with
fine tune control. The SY89295U and SY89296U are part
of Micrel’s high-speed, Precision Edge product line.
