2.5V/3.3V 1.5GHz Precision LVPECL
Programmable Delay General Description
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
Â±5% or 3.3V Â±10% power supply, and is guaranteed over
the full industrial temperature range (â€“40Â°C to +85Â°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 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 require an analog delay input, see the
SY89296L which is a programmable delay chip with fine
tune control. The SY89295U and SY89296U are part of
Micrelâ€™s high-speed, Precision Edge product line.
