2 / 12 page  10MHz to 1050MHz Integrated RF Oscillator with Buffered Outputs 2 _______________________________________________________________________________________ ABSOLUTE MAXIMUM RATINGS DC ELECTRICAL CHARACTERISTICS (VCC1, VCC2 = +2.7V to +5.25V, FDBK = open, TANK = open, OUT and OUT connected to VCC through 50Ω, SHDN = 2V, TA = -40°C to +85°C, unless otherwise noted. Typical values measured at VCC1 = VCC2 = 3.0V, TA = +25°C.) (Note 1) AC ELECTRICAL CHARACTERISTICS (Per Test Circuit of Figure 1, VCC = +3.0V, SHDN = VCC, ZLOAD = ZSOURCE = 50Ω, PIN = -20dBm (50Ω), fTEST = 900MHz, TA = +25°C, unless otherwise noted.) Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. VCC1, VCC2 to GND................................................-0.3V to +6V TANK, SHDN to GND .................................-0.3V to (VCC + 0.3V) OUT, OUT to GND...........................(VCC - 0.6V) to (VCC + 0.3V) FDBK to GND ..................................(VCC - 2.0V) to (VCC + 0.3V) Continuous Power Dissipation (TA = +70°C) µMAX (derate 5.7mW/°C above +70°C) .....................457mW Operating Temperature Range MAX2620EUA .................................................-40°C to +85°C Junction Temperature ......................................................+150°C Storage Temperature Range .............................-65°C to +165°C Lead Temperature (soldering, 10sec) .............................+300°C µA 0.1 2 SHDN = 0.6V Shutdown Current mA 9.0 12.5 UNITS MIN TYP MAX CONDITIONS PARAMETER Supply Current V 2.0 Shutdown Input Voltage High V 0.6 Shutdown Input Voltage Low µA 5.5 20 SHDN = 2.0V Shutdown Bias Current High µA 0.5 SHDN = 0.6V Shutdown Bias Current Low MHz 10 1050 TA = -40°C to +85°C (Note 2) UNITS MIN TYP MAX CONDITIONS PARAMETER Frequency Range dB 50 OUT or OUT to TANK; OUT, OUT driven at P = -20dBm Reverse Isolation dB 33 OUT to OUT Output Isolation Note 2: Guaranteed by design and characterization at 10MHz, 650MHz, 900MHz, and 1050MHz. Over this frequency range, the magnitude of the negative real impedance measured at TANK is greater than one-tenth the magnitude of the reactive impedances at TANK. This implies proper oscillator start-up when using an external resonator tank circuit with Q > 10. C3 and C4 must be tuned for operation at the desired frequency. Note 1: Specifications are production tested and guaranteed at TA = +25°C and TA = +85°C. Specifications are guaranteed by design and characterization at TA = -40°C. |
