PARAMETER TEST CONDITIONS MIN TYP MAX UNIT f = 125 MHz, Input slew rate ≥ 3 V/ns 10 kHz offset -155 100 kHz offset -162 PNFLOOR Phase Noise Floor (10) dBc/Hz 1 MHz offset -166 10 MHz offset -166 20 MHz offset -166 REF = CLK/nCLK 45% 55% ODC Output Duty Cycle(11)(12) REF = LVCMOS_CLK, 45% 55% f ≤ 300 MHz tEN Output Enable Time 5 ns tDIS Output Disable Time 5 ns (10) Buffer Phase Noise Floor: PNFLOOR (dBc/Hz) = 10 x log10[10^(PNSYSTEM/10) – 10^(PNSOURCE/10)], where PNSYSTEM is the phase noise floor of the system output (source+buffer) and PNSOURCE is the phase noise floor of the input source. Buffer Phase Noise Floor should be considered only when the input source noise floor is 3 dB or better than the buffer noise floor (PNFLOOR). This is usually the case for high-quality ultra-low-noise oscillators. Please refer to System-Level Phase Noise and Additive Jitter Measurement for input source and measurement details. (11) These AC parameters are specified by design. Not tested in production (12) 50% Input duty cycle 7.10 Electrical Characteristics (VDDO = 2.5 V ± 5%) Over recommended operating free-air temperature range (unless otherwise noted), VDD = 3.3V ± 5%, VDDO = 2.5V ± 5%, All AC parameters measured at ≤ 350 MHz unless otherwise noted. PARAMETER TEST CONDITIONS MIN TYP MAX UNIT fOUT Maximum Output Frequency(1) (2) 350 MHz tPDLH Propagation Delay, LVCMOS_CLK(4), 0°C to 70°C 1.1 2.1 ns CLK/nCLK(5) Low to High(3) –40°C to 85°C 0.95 2.2 tSK(O) Output Skew(2)(6)(7) Measured on rising edge 35 ps tSK(PP) Part-to-Part Skew (3)(7)(8) 700 ps tR/tF Output Rise/Fall Time (3) 20% to 80% 50 700 ps JADD Additive Jitter(9) f=125 MHz, 0.04 ps RMS Input slew rate ≥ 3 V/ns, 12 kHz to 20 MHz integration band ODC Output Duty Cycle(3)(10) REF = CLK/nCLK 45% 55% REF = LVCMOS_CLK, 45% 55% f ≤ 300 MHz tEN Output Enable Time 5 ns tDIS Output Disable Time 5 ns (1) There is no minimum input / output frequency provided the input slew rate is sufficiently fast. Refer to Input Slew Rate Considerations. (2) These AC parameters are specified by characterization. Not tested in production. (3) These AC parameters are specified by design. Not tested in production. (4) Measured from the VDD/2 of the input to the VDDO/2 of the output. (5) Measured from the differential input crossing point to VDDO/2 of the output. (6) Defined as skew between outputs at the same supply voltage and with equal loading conditions. Measured at VDDO/2 of the output. (7) Parameter is defined in accordance with JEDEC Standard 65. (8) Calculation for part-to-part skew is the difference between the fastest and slowest tPD across multiple devices, operating at the same supply voltage, same frequency, same temperature, with equal load conditions, and using the same type of inputs on each device. (9) Buffer Additive Jitter: JADD = SQRT(JSYSTEM 2 - J SOURCE 2), where J SYSTEM is the RMS jitter of the system output (source+buffer) and JSOURCE is the RMS jitter of the input source, and system output noise is not correlated to the input source noise. Additive jitter should be considered only when the input source noise floor is 3 dB or better than the buffer noise floor (PNFLOOR). This is usually the case for high-quality ultra-low-noise oscillators. Please refer to System-Level Phase Noise and Additive Jitter Measurement for input source and measurement details.
