Parameter Min Typ Max Unit Test Conditions/Comments CLOCK INPUTS (CLK, CLK) Differential input Input Frequency 01 2.4 GHz High frequency distribution (VCO divider) 01 1.6 GHz Distribution only (VCO divider bypassed) Input Sensitivity, Differential 150 mV p-p Measured at 2.4 GHz; jitter performance is improved with slew rates > 1 V/ns Input Level, Differential 2 V p-p Larger voltage swings may turn on the protection diodes and may degrade jitter performance Input Common-Mode Voltage, VCM 1.3 1.57 1.8 V Self-biased; enables ac coupling Input Common-Mode Range, VCMR 1.3 1.8 V With 200 mV p-p signal applied; dc-coupled Input Sensitivity, Single-Ended 150 mV p-p CLK ac-coupled; CLK ac-bypassed to RF ground Input Resistance 3.9 4.7 5.7 kΩ Self-biased Input Capacitance 2 pF 1 Below about 1 MHz, the input should be dc-coupled. Care should be taken to match VCM. CLOCK OUTPUTS Table 4. Parameter Min Typ Max Unit Test Conditions/Comments LVPECL CLOCK OUTPUTS Termination = 50 Ω to VS − 2 V OUT0, OUT1, OUT2, OUT3, OUT4, OUT5 Differential (OUT, OUT) Output Frequency, Maximum 2950 MHz Using direct to output; see Figure 25 for peak-to– peak differential amplitude Output High Voltage (VOH) VS − 1.12 VS − 0.98 VS − 0.84 V Output Low Voltage (VOL) VS − 2.03 VS − 1.77 VS − 1.49 V Output Differential Voltage (VOD) 550 790 980 mV VOH − VOL for each leg of a differential pair for default amplitude setting with driver not toggling; see Figure 25 for variation over frequency LVDS CLOCK OUTPUTS Differential termination 100 Ω at 3.5 mA OUT6, OUT7, OUT8, OUT9 Differential (OUT, OUT) Output Frequency 800 MHz The AD9516 outputs toggle at higher frequencies, but the output amplitude may not meet the VOD specification; see Figure 26 Differential Output Voltage (VOD) 247 360 454 mV VOH − VOL measurement across a differential pair at the default amplitude setting with output driver not toggling; see Figure 26 for variation over frequency Delta VOD 25 mV This is the absolute value of the difference between VOD when the normal output is high vs. when the complementary output is high Output Offset Voltage (VOS) 1.125 1.24 1.375 V (VOH + VOL)/2 across a differential pair Delta VOS 25 mV This is the absolute value of the difference between VOS when the normal output is high vs. when the complementary output is high Short-Circuit Current (ISA, ISB) 14 24 mA Output shorted to GND CMOS CLOCK OUTPUTS OUT6A, OUT6B, OUT7A, OUT7B, OUT8A, OUT8B, OUT9A, OUT9B Single-ended; termination = 10 pF Output Frequency 250 MHz See Figure 27 Output Voltage High (VOH) VS − 0.1 V At 1 mA load Output Voltage Low (VOL) 0.1 V At 1 mA load |
