DESCRIPTION
The TSOP75D25 is an SMD IR receiver module for 3D
sychronisation signals. The receiver is designed to operate
at a carrier frequency of 25 kHz and a wavelength of 830 nm
to avoid interference with standard remote control systems
at 940 nm and 30 kHz to 56 kHz. The TSOP75D25 can
receive continuously transmitted signal patterns with a
minimum burst length of 6 cycles and frame rates up to
200 Hz. The circuit provides good suppression of optical
noise from CFLs, LCD backlight and plasma panels.

SUITABLE DATA FORMAT
The TSOP75D25 is designed to suppress spurious output
pulses due to noise or disturbance signals. Data and
disturbance signals can be distinguished by the devices
according to carrier frequency, burst length and envelope
duty cycle. The data signal should be close to the
band-pass center frequency (e.g. 25 kHz) and fulfill the
conditions in the table below.
When a data signal is applied to the TSOP75D25 in the
presence of a disturbance signal, the sensitivity of the
receiver is reduced to insure that no spurious pulses are
present at the output. Some examples of disturbance
signals which are suppressed are
• DC light (e.g. from tungsten bulb or sunlight)
• Continuous signals at any frequency
• Strongly or weakly modulated noise from fluorescent
lamps with electronic ballasts (see figure 15 or figure 16)

LABEL
Standard bar code labels for finished goods
The standard bar code labels are product labels and used
for identification of goods. The finished goods are packed in
final packing area. The standard packing units are labeled
with standard bar code labels before transported as finished
goods to warehouses. The labels are on each packing unit
and contain Vishay Semiconductor GmbH specific data.
