DESCRIPTION
The TSOP773..W is a miniaturized receiver module for
infrared remote control systems. One PIN diode per lens and
a preamplifier are assembled on a leadframe, the epoxy lens
cap is designed as an IR filter.
The demodulated output signal can be directly decoded by
a microprocessor. The TSOP773..W is optimized to better
suppress spurious pulses from fluorescent lamps, LCD,
TVs, or plasma displays.
This component has not been qualified according to
automotive specifications.

SUITABLE DATA FORMAT
The TSOP773..W 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. 40 kHz) and fulfill the
conditions in the table below.
When a data signal is applied to the TSOP773..W 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 fig. 15 or fig. 16)

suppression.
