General Description
The HMCAD5831LP9BE is a wideband 3-bit analog-
to-digital converter with over/under range bit. The
converter operates at speeds up to 26 GS/s with a
Nyquist input. Reference ladder end voltages are set
externally by the user allowing the user to customize
input common mode and swing levels. ADC outputs
can be forced to 0 by using the Data Inhibit function.
Output data can be modulated by an external clock
viawww.DataSheet.net/ the XOR CML input. The HMCAD5831LP9BE also
features a 1:2 demux with half rate clock output. The
output bits are binary weighted, where X2 and Y2 are
the MSBs. The single-ended RF input can be AC or DC
coupled and supports broadband operation.
The HMCAD5831LP9BE operates from -5 V and -3.3 V
supplies and is available in ROHS-compliant 9 x 9 mm
SMT package.

Data
D0 = A0 xor X0
D1 = A1 xor X0
D2 = A2 xor X1
D3 = A3 xor X1
D4 = A4 xor X2
D5 = A5 xor X2
Data
D0 = A0 xor X0
D1 = A1 xor X1
D2 = A2 xor X1
D3 = A3 xor X2
D4 = A4 xor X2
D5 = A5 xor X3
The FPGA aligns the data with the X side leading. In the incorrect case, a 1-bit shift is caused by the
1 clock cycle delay in the XOR.

131499 Evaluation Board
[1] Reference this number when ordering complete evaluation PCB
[2] Circuit Board Material: Arlon 25FR or Rogers 4350
The circuit board used in the application should
use RF circuit design techniques. Signal lines
should have 50 ohm impedance while the package
ground leads should be connected directly to the
ground plane similar to that shown. The exposed
metal package base must be connected to AVEE.
A sufficient number of via holes should be used to
connect the top and bottom ground planes. The
evaluation circuit board shown is available from
Hittite upon request.
