4 / 20 page AD9550 Rev. 0 | Page 4 of 20 Parameter Min Typ Max Unit Test Conditions/Comments ×2 Frequency Multiplier 125 MHz To avoid excessive reference spurs, the ×2 multiplier requires 48% to 52% duty cycle; reference clock input frequencies greater than 125 MHz require the use of the divide-by-5 prescaler VCO CHARACTERISTICS Frequency Range 3350 4050 MHz VCO Gain 45 MHz/V VCO Tracking Range ±300 ppm PLL Lock Time Using the pin selected frequency settings; lock time is from the rising edge of the RESET pin to the rising edge of the LOCKED pin Low Bandwidth Setting (170 Hz) Applies for Pin A3 to Pin A0 = 0001 to 1100, or for Pin A3 to Pin A0 = 1111 13.3 kHz PFD Frequency 214 ms 16 kHz PFD Frequency 176 ms Medium Bandwidth Setting (20 kHz) Applies for Pin A3 to Pin A0 = 1110 and Pin Y5 to Pin Y0= 111111 1.5625 MHz PFD Frequency 2 ms High Bandwidth Setting (75 kHz) Applies for Pin A3 to Pin A0 = 1101 to 1110 2.64 MHz PFD Frequency 1.50 ms 4.86 MHz PFD Frequency 0.89 ms 1 The A3 to A0 and Y5 to Y0 pins have 100 kΩ internal pull-up resistors. The OM2 to OM0 pins have 40 kΩ pull-up resistors. 2 The RESET pin has a 100 kΩ internal pull-up resistor. OUTPUT CHARACTERISTICS Table 2.
