SL2150F Demonstration Board
The SL2150F demonstration board is designed to allow testing of device functionality as a stand alone power
splitter. It allows for testing of the AGC function and independent testing of all channels.
The SL2150F is designed to interface differentially into a silicon tuner such as the SL2101 with simple inductive or
resistive pull-ups. However, to facilitate testing the differential, output is converted to a single ended signal through
a balun. The differential conversion is necessary for achieving second order performance.
All outputs require a DC return path to Vcc to prevent output saturation. This can be provided by the balun, inductive
pull up or resistive pull up. In the case of a resistive pull up, the maximum load value is 38
.
The balun also provides the DC bias to the outputs; all outputs have to be DC 'shorted' to Vcc to prevent saturation
of the output stages.
All input and output terminations are 75
.
The board schematic and layout are contained in Figure 19 - "Test Board Schematic" and Figure 20 - "Test Board
Layout" respectively.
Operation note
The supply voltage must be connected and enabled before any AGC voltage is applied unless the AGC
supplies are current limited to <1 mA or else permanent damage may occur through the ESD structures on
the device.
4.1
Pin Connections
All references are with the board oriented as in bottom view on Figure 1 - "SL2150F Block Diagram". Pin 1 of the
header is defined as the left-hand pin.
4.2
Power Supply
A single 5V supply is required. Power is supplied through the two-pin header PL1, located top right hand corner.
4.3
RF Input
The RF input F type, SK1, is located on the right hand side of the board.
4.4
RF Outputs
Output 1 is the upper of the two F type connectors, SK3, located on the left-hand side.
Output 2 is the lower of the two F type connector, SK4, located on the left-hand side.
Output 3 is the F type connector, SK5, located at the bottom of the board
Output 4 is the F type connector, SK2, located at the top of the board.
