Laser Driver for Projectors
Video Input Buffers Equation 1:
The synchronous video data inputs (D0 to D9, SYNC,
FFh ? ? FFh ?
D0 to D9, PO, and SYNC can be left open. SYNC can
be connected to REF if not used (for reduced power
consumption).
Video Demultiplexer
The video demultiplexer (Figure 7) can accommo-
date configurations as shown in the Typical Operating
Circuits . In Configuration 1 (Figure 19), 10-bit red, green,
and blue video data is time multiplexed. The SYNC sig-
nal is used to demultiplex the video data.
In Configuration 2 (Figure 21), each output driver uses
VIDEO2 as a data source.
Driver Outputs
The driver outputs provide currents to the lasers as
shown in Figure 8.
The transfer characteristic of the driver outputs is shown
in Figure 10 and Equation 1.
Table 2. Driver Output Typical Parameter
Summary
where:
? Current into the laser driver is positive (out is negative)
? VIDEO is the 10-bit video input
? gs is the 8-bit gain setting register
? os is the 8-bit offset setting register
? G LOW is the minimum gain (mA)
? (G LOW + G HIGH ) is the maximum gain (mA)
? OS HIGH is the maximum offset (mA)
? OS LOW is the minimum offset (mA)
The output compliance voltage (V C_ = V A_ - V OUT_ ,
Figure 9) defines the output voltage required to obtain
low overshoot and fast settling time.
Table 2 summarizes the typical output current capability
for each driver output. Table 3 summarizes the maximum
ratings for each driver output.
