SY89295U 2.5V/3.3V 1.5GHz Precision LVPECL Programmable Delay General Description The SY89295U is a programmable delay line that delays Precision Edge the input signal using a digital control signal. The delay Features can vary from 3.2ns to 14.8ns in 10ps increments. In addition, the input signal is LVPECL, uses either a 2.5V Precision LVPECL programmable delay line 5% or 3.3V 10% power supply, and is guaranteed over Guaranteed AC performance over temperature and the full industrial temperature range (40C to +85C). voltage: The delay varies in discrete steps based on a control word. >1.5GHz f MAX The control word is 10-bits long and controls the delay in <160ps rise/fall times 10ps increments. The eleventh bit is D 10 and is used to simultaneously cascade the SY89295U which allows for a Low-jitter design: larger delay range. In addition, the input pins IN and /IN <10ps total jitter PP default to an equivalent low state when left floating. <2ps cycle-to-cycle jitter RMS Further, for maximum flexibility, the control register interface accepts CMOS or TTL level signals. <1ps random jitter RMS For applications that require an analog delay input, see the Programmable delay range: 3.2ns to 14.8ns in 10ps SY89296L which is a programmable delay chip with fine increments tune control. The SY89295U and SY89296U are part of Increased monotonicity over the MIC100EP195 product line.
