MICROCHIP SY89296UMG

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.
