OPERATIONAL DESCRIPTION
3D7205 five-tap delay line architecture shown Figure delay line composed number delay cells connected series. Each delay cell produces output replica signal present input, shifted time. delay cells matched share same compensation signals, which minimizes tap-totap delay deviations over temperature supply voltage variations. guarantee Table delay accuracy input frequencies higher than Maximum Operating Frequency, 3D7205 must tested user operating frequency. Therefore, facilitate production device identification, part number will include custom reference designator identifying intended frequency operation. programmed delay accuracy device guaranteed, therefore, only user specified input frequency. Small input frequency variation about selected frequency will only marginally impact programmed delay accuracy, all. Nevertheless, strongly recommended that engineering staff DATA DELAY DEVICES consulted.
INPUT SIGNAL CHARACTERISTICS
Frequency and/or Pulse Width (high low) operation adversely impact specified delay accuracy particular device. reasons dependency output delay accuracy input signal characteristics varied complex. Therefore Maximum Absolute Maximum operating input frequency Minimum Absolute Minimum operating pulse width have been specified.
OPERATING PULSE WIDTH
Absolute Minimum Operating Pulse Width (high low) specification, tabulated Table determines smallest Pulse Width delay line input signal that reproduced, shifted time device output, with acceptable pulse width distortion. Minimum Operating Pulse Width (high low) specification determines smallest Pulse Width delay line input signal which output delay accuracy tabulated Table guaranteed. guarantee Table delay accuracy input pulse width smaller than Minimum Operating Pulse Width, 3D7205 must tested user operating pulse width. Therefore, facilitate production device identification, part number will include
OPERATING FREQUENCY
Absolute Maximum Operating Frequency specification, tabulated Table determines highest frequency delay line input signal that reproduced, shifted time device output, with acceptable duty cycle distortion. Maximum Operating Frequency specification determines highest frequency delay line input signal which output delay accuracy guaranteed.
