IDT5V926A

Single Output Clock Generator IDT5V926A DATA SHEET FEATURES: • 3V to 3.6V operating voltage • 48MHz to 160MHz output frequency range • Input from fundamental crystal oscillator or external source • Internal PLL feedback (loading the feedback output relative to the other outputs, will adjust the propagation delay between REF inputs and outputs) • Select inputs (S[1:0]) for FB divide selection (multiply ratio of 2, 3, 4, 4.25, 5, 6, 6.25, and 8) • Low jitter • PLL bypass for testing and power-down control (S1 = H, S0 = H, powers part down 125MHz QREF Output/Duty Cycle VT = VDDQ/2 FOUT = 106.25MHz tJ fOUT Cycle - Cycle Jitter FOUT = 125MHz FOUT = 155.52MHz Output Frequency INPUT TIMING REQUIREMENTS Symbol tR, tF tPWC DH fOSC fIN NOTES: 1. Where pulse width implied by DH is less than the tPWC limit, tPWC limit applies. 2. When using a clock input.
