7 / 205 page  Data Sheet AD9546 Rev. 0 | Page 7 of 205 SPECIFICATIONS The minimum and maximum values apply for the full range of supply voltage and operating temperature variations. Typical values apply for VDD = 1.8 V and TA= 25°C, unless otherwise noted. OPERATING TEMPERATURE Table 1. Parameter Min Typ Max Unit Test Conditions/Comments OPERATING TEMPERATURE Ambient Temperature1 −40 +85 °C Die Temperature2 +105 °C Internal temperature sensor readings exceeding 105°C indicate excessive die temperature 1 See the Thermal Resistance section for additional information. 2 The maximum die temperature supports the performance stated in Table 2 to Table 39. The maximum operating die temperature takes precedence over the maximum ambient operating temperature. Use the internal temperature sensor to measure the AD9546 die temperature (see the Temperature Sensor section). SUPPLY VOLTAGE Table 2. Parameter Min Typ Max Unit Test Conditions/Comments SUPPLY VOLTAGE VDDIOA and VDDIOB 1.71 1.8 3.465 V 1.8 V, 2.5 V, and 3.3 V operation supported VDD 1.71 1.8 1.89 V SUPPLY CURRENT The minimum, typical, and maximum supply current values given in Table 3 are for the minimum, typical, and maximum supply voltage specifications in Table 2. Table 3. Parameter Min Typ Max Unit Test Conditions/Comments SUPPLY CURRENT FOR TYPICAL CONFIGURATION Uses the Typical Configuration conditions in Table 4 VDDIOx Current (IVDDIOx) 5 8 mA Aggregate current for all VDDIOx pins (where x = A or B) VDD Current (IVDD) 325 330 mA Aggregate current for all VDD pins SUPPLY CURRENT FOR LINE CARD CONFIGURATION Uses the Line Card Configuration conditions in Table 4; see the Digitized Clocking Application section for line card information IVDDIOx 5 8 mA Aggregate current for all VDDIOx pins (where x = A or B) IVDD 325 330 mA Aggregate current for all VDD pins SUPPLY CURRENT FOR TIMING CARD CONFIGURATION Uses the Timing Card Configuration conditions in Table 4; see the Digitized Clocking Application section for timing card information IVDDIOx 5 8 mA Aggregate current for all VDDIOx pins (where x = A or B) IVDD 325 330 mA Aggregate current for all VDD pins SUPPLY CURRENT FOR ALL BLOCKS RUNNING CONFIGURATION Uses the All Blocks Running Configuration conditions in Table 4 IVDDIOx 5 8 mA Aggregate current for all VDDIOx pins (where x = A or B) IVDD 410 440 mA Aggregate current for all VDD pins |
