General Description

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 ±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 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,

see the SY89295U. The SY89295U and SY89296U are

part of Micrel’s high-speed, Precision Edge® product line.
