A PIN diode and a preamplifier are assembled on a lead frame, the epoxy package contains an IR filter. ORDERING CODE The demodulated output can be directly connected to a UART or a microprocessor. The TSDP34138 may be used for continuous reception of data according to RS-232 at 4800 bps in noise free environments. Higher data rate RS-232 may require data monitoring of gain levels. Non RS-232 codings may be used to achieve continuous average data rates up to 7800 bps in noisy ambients.

The devices can distinguish data signals from noise due to differences in frequency, burst length, and envelope duty cycle. For optimum sensitivity, the data’s modulation frequency should be close to the device’s band-pass center frequency (e.g. 38.4 kHz) and fulfill the conditions in the table below. 10000 7 When a data signal is applied to the receiver in the presence of noise, the sensitivity of the receiver is automatically reduced by the AGC to insure that no spurious pulses are present at the receiver’s output. Some examples of noise which is suppressed: 5 1000 1st line 2nd line 2nd line IR Signal Amplitude 6 4 3 100 2 1 • DC light (e.g. from tungsten bulbs sunlight) 10 0 0 • Continuous signals at any frequency 5 15 20 Time (ms) 16920 • Strongly or weakly modulated patterns from fluorescent lamps with electronic ballasts (see Fig. 13 or Fig. 14). 10 Fig. 13 - IR Disturbance from Fluorescent Lamp With Low Modulation Axis Title 10000 40 1000 0 1st line 2nd line 2nd line IR Signal Amplitude 20 -20 100 -40 10 -60 0 5 10 15 20 Time (ms) 16921 Fig. 14 - IR Disturbance from Fluorescent Lamp With High Modulation TSDP341..
