ADF4360-8BCPZ

The absolute maximum ratings of the ADF4360-8BCPZ can be summarized as:(1)AVDD to GND:0.3V to +3.9 V;(2)storage temperature range:-65 to +150;(3)operating temperature range:-40 to 85;(4)AVDD to DVdd:-0.3V to +0.3V;(5)maximum junction temperature:150.Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only; functional operation of the device at these or any other conditions above those indicated in the operational section of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.During initial power-up, a write to the control latch powers up the part, and the bias currents of the VCO begin to settle. If these currents have not settled to within 10% of their steady-state value, and if the N counter latch is then programmed, the VCO may not oscillate at the desired frequency, which does not allow the band select logic to choose the correct frequency band, and the ADF4360-8 may not achieve lock. If the recom-mended interval is inserted, and the N counter latch is pro-grammed, the band select logic can choose the correct fre-quency band, and the part locks to the correct frequency.
