4 / 31 page 4 T4260 4528G–AUDR–12/03 Absolute Maximum Ratings Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. All voltages are referred to GND Parameters Symbol Value Unit Analog supply voltage Pins 15 and 41 V ST, VSPLL 10 V Maximum power consumption P tot 1.0 W Ambient temperature range T amb -40 to +85 ° C Storage temperature range T stg -40 to +150 ° C Junction temperature T j 150 ° C Thermal Resistance Parameters Symbol Value Unit Junction ambient, soldered to PCB R thJA 52 K/W Operating Range Parameters Symbol Min. Typ. Max. Unit Supply voltage range (1) Pins 15 and 41 V ST, VSPLL 88.5 10 V Ambient temperature T amb -40 85 ° C Oscillator frequency Pin 21 R fi 60 175 MHz Note: 1. V ST and VSPLL must have the same voltage. Electrical Characteristics Test conditions (unless otherwise specified): V ST/VSPLL = +8.5 V, Tamb = +25° C No. Parameters Test Conditions Pin Symbol Min.
