1 / 10 page 1 PS8449A 10/09/00 Features PI6C3Q99X family provides following products: PI6C3Q991:32-pinPLCCversion PI6C3Q993:28-pinQSOPversion Inputs are 5V I/O Tolerant 4 pairs of programmable skew outputs Low skew: 200ps same pair; 250ps all outputs Selectable positive or negative edge synchronization: Excellent for DSP applications Synchronous output enable Output frequency: 3.75 MHz to 85 MHz 2x, 4x, 1/2, and 1/4 outputs 3 skew grades: 3-level inputs for skew and PLL range control PLL bypass for DC testing Externalfeedback,internalloopfilter 12mA balanced drive outputs Low Jitter: < 200ps peak-to-peak Industrial temperature range Pin-to-pincompatiblewithIDTQS5V991andQS5V993 Availablein32-pinPLCCand28-pinQSOP Description ThePI6C3Q99Xfamilyisahighfanout3.3VPLL-basedclockdriver intended for high performance computing and data-communica- tions applications. A key feature of the programmable skew is the abilityofoutputstoleadorlagtheREFinputsignal.ThePI6C3Q991 has 8 programmable skew outputs in 4 banks of 2, while the PI6C3Q993 has 6 programmable skew outputs and 2 zero skew outputs.Skewiscontrolledby3-levelinputsignalsthatmaybehard- wiredtoappropriateHIGH-MID-LOWlevels. When the GND/sOE pin is held low, all the outputs are synchro- nously enabled. However, if GND/sOE is held high, all the outputs except3Q0and3Q1aresynchronouslydisabled.Furthermore,when the V CCQ/PE is held high, all the outputs are synchronized with the positive edge of the REF clock input. When VCCQ /PE is held low, alltheoutputsaresynchronizedwiththenegativeedgeof REF.Both devices have LVTTL outputs with 12mA balanced drive outputs.
