FUNCTIONAL DESCRIPTION
PDU15F-series device 5-bit digitally programmable delay line. delay, TDA, from input (IN) output pins (OUT, OUT/) depends address code (A4-A0) according following formula: TINC
DESCRIPTIONS
OUT/ A0-A4 Delay Line Input Non-inverted Output Inverted Output Address Bits Output Enable Volts Ground
where address code, TINC incremental delay device, inherent delay device. incremental delay specified dash number device range from 0.5ns through 20ns, inclusively. enable pins (EN/) held during normal operation. These pins must always same state tied together externally. When these signals brought HIGH, OUT/ forced into HIGH states, respectively. address latched must remain asserted during normal operation.

APPLICATION NOTES
ADDRESS UPDATE
PDU15F memory device. such, special precautions must taken when changing delay address order prevent spurious output signals. timing restrictions shown Figure After last signal edge delayed appeared pin, minimum time, TOAX, required before address lines change. This time given following relation: TOAX i-1) TINC where address codes, respectively. Violation this constraint may, depending history input signal, cause spurious signals appear pin. possibility spurious signals persists until required TOAX elapsed. similar situation occurs when using signal disable output while active. this case, unit must held disabled state until device able "clear" itself. This achieved holding signal high signal time given TDISH TINC Violation this constraint may, depending history input signal, cause spurious signals appear pin. possibility spurious signals persists until required TDISH elapsed.
INPUT RESTRICTIONS
There three types restrictions input pulse width period listed Characteristics table. recommended conditions those which delay tolerance specifications monotonicity guaranteed. suggested conditions those which signals will propagate through unit without significant distortion. absolute conditions those which unit will produce some type output given input. When operating unit between recommended absolute conditions, delays deviate from their values frequency. However, these deviations will remain constant from pulse pulse input pulse width period remain fixed. other words, delay unit exhibits frequency pulse width dependence when operated beyond recommended conditions. Please consult technical staff Data Delay Devices your application specific high-frequency requirements. Please note that increment tolerances listed represent design goal. Although most delay increments will fall within tolerance, they guaranteed throughout address range unit. Monotonicity however, guaranteed over addresses.
