FEATURES  
DESCRIPTION  
16 Variable Gain Amplifiers (VGA)  
16 Single-Ended Buffered Inputs With 1VPP  
Maximum Swing  
The AFE5851 is an analog front-end targeting  
applications where the power and level of integration  
are critical. The device contains 16 variable gain  
amplifiers (VGA), followed by an octal high speed (up  
to 65 MSPS) analog to digital converter (ADC).  
5.5nV/Hz VCA Input Noise (31dB Gain).  
Variable Gain –5dB to 31dB With 0.125dB  
Steps  
Each of the 16 single ended inputs is buffered,  
accepts up to 1VPP maximum input swing and it is  
followed by a VGA with a gain range from –5dB to  
31dB. The VGA gain is digitally controlled and the  
gain curves versus time can be stored in memory,  
integrated within the device using the serial interface.  
Digital Gain Control  
3rd Order Anti-Aliasing Filter With  
Programmable Cut-Off Frequency (7.5, 10 and  
14MHz).  
Clamping  
A selectable clamping and anti-alias low pass filter  
(with 3dB attenuation at 7.5, 10 or 14MHz) is also  
integrated between the VGA and ADC for every  
channel. The VGA/anti-alias filter outputs are  
differential (limited to 2 VPP) and drive the on-board  
12-bit 65MSPS ADC that is shared between two  
VGAs to optimize the power dissipation. Each VGA  
output is sampled at alternate clock cycles, making  
the effective sampling frequency half the input clock  
rate. The ADC also scales down its power

a lower sampling rate be  
Serial LVDS Outputs  
1.8V and 3.3V Supply  
The ADC outputs are serialized in LVDS streams  
further minimizing power and board area. The  
AFE5851 is available in a 64-pin QFN package  
(9x9mm2) and is specified over the full industrial  
temperature range (–40°C to 85°C).
