Status: In Production
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 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 Micrel's high-speed, Precision Edge® product line.
