13 / 28 page ![]() Data Sheet AD9515 Rev. B | Page 13 of 28 PIN CONFIGURATION AND FUNCTION DESCRIPTIONS 1 VS 2 CLK 3 CLKB 4 VS 5 SYNCB 6 VREF 7 S10 8 S9 18 OUT1B 19 OUT1 20 VS 21 VS 22 OUT0B 23 OUT0 24 VS 17 VS TOP VIEW (Not to Scale) AD9515 NOTES 1. THE EXPOSED PADDLE ON THIS PACKAGE IS AN ELECTRI- CAL CONNECTION AS WELL AS A THERMAL ENHANCEMENT. FOR THE DEVICE TO FUNCTION PROPERLY, THE PADDLE MUST BE SOLDERED TO A PCB LAND THAT FUNCTIONS AS BOTH A HEAT DISSIPATION PATH AS WELL AS AN ELECTRICAL GROUND (ANALOG). Figure 6. 32-Lead LFCSP Pin Configuration Table 9. Pin Function Descriptions Pin No. Mnemonic Description 1, 4, 17, 20, 21, 24, 26, 29, 30 VS Power Supply (3.3 V). 2 CLK Clock Input. 3 CLKB Complementary Clock Input. Used in conjunction with CLK. 5 SYNCB Used to Synchronize the Outputs; Active Low Signal. 6 VREF Provides 2/3 VS Reference Voltage for Use with Programming Pins S0 to S10. 25, 16, 15, 14, 13, 12, 11, 10, 9, 8, 7 S0 to S10 Programming Pins. These pins determine the operation of the AD9515; 4-state logic. 18 OUT1B Complementary LVDS/Inverted CMOS Output. Includes a delay block. 19 OUT1 LVDS/CMOS Output. Includes a delay block. 22 OUT0B Complementary LVPECL Output. 23 OUT0 LVPECL Output. 27, 28 DNC Do Not Connect. 31, Exposed Paddle GND Ground. The exposed paddle on the back of the chip is also GND. 32 RSET Current Sets Resistor to Ground. Nominal value = 4.12 kΩ. |
