1. Description
The AT84AS001 is a high performance 12-bit, 500 Msps ADC featuring low power consumption and true 12-bit linearity for IF sampling applications. By using its on-chip S/H circuity and advanced high speed process technology, it allows for sampling rates up to 500 Msps at a center frequency of 150 MHz and IF band of 100 MHz. Its electrical performance is coupled with ease of integration into new or existing designs by such features as AC or DC coupled analog input, differential LVDS compatible output, 3-wire serial programming interface (gain control, offset control, standby mode and Built-In-Test), Double Data Rate clock output and synchronous reset input.

2. Functional Description
The AT84AS001 is a monolithic 12-bit 500 Msps ADC. The circuit includes an on-chip Sample and Hold (S/H), and a 12-bit analog-to-digital converter core. The output data is LVDS (100) compliant. A 3-wire serial interface (3-bit address, 16-bit data) is included to provide several adjustments and controls: * * * Gain: 1.5 dB full-scale digital control (8-bit-control) Offset: 40 LSB digital control (8-bit control) Standby mode for power saving
The AT84AS001 features a full-power input bandwidth of 1.5 GHz

4. Implementing the AT84AS001 ADC
4.1 Analog Input Implementation in AC Coupled Mode
The analog inputs of the ADC were designed with a double pad implementation as illustrated in the following schema, Figure 4-1. The reverse pad for each input should be tied to ground via a capacitor of 10 nF and a 50 resistor. In this mode, the VSCH output pin is left open. Figure 4-1. AC Analog Inputs Termination Methods

4.2 Analog Input implementation in DC Coupled Mode
In order to set the DC analog input, voltage the VCSH output pin must be used as described in Figure 4-2. The impedance Zout//R1 must be lower than 2 k and equal to 50 to guarantee good impedance matching and to apply correct analog input level. Figure 4-2. DC Analog Inputs Termination Methods

Board Reflowed Sn/Pb/Ag 62/36/2 Eutectic Solder Balls
Due to package weight, the balls "collapse" somewhat during reflow, and the height of the balls is reduced by approximately 0.10 mm. The balls increase simultaneously in diameter to compensate.
Notes:
1. The copper heat spreader is connected to the ADC circuit GND through a conductive low resistivity die attach. 2. For RoHS version, please contact your local Atmel Sales Office.
