DESCRIPTION
The TSOP312.., TSOP314..series are miniaturized IR receiver modules for infrared remote control systems. A PIN diode and a preamplifier are assembled on a leadframe, the epoxy package contains an IR filter.
The demodulated output signal can be directly connected to a microprocessor for decoding.
The TSOP312.., TSOP314.. are optimized to suppress almost all spurious pulses from energy saving lamps like CFLs. The AGC4 used in the TSOP314.. may suppress some data signals. The TSOP312.. is a legacy product for all common IR remote control data formats. Between these two receiver types, the TSOP314.. is preferred. Customers should initially try the TSOP314.. in their design.
These components have not been qualified according to automotive specifications.

SUITABLE DATA FORMAT
This series is designed to suppress spurious output pulses due to noise or disturbance signals. The devices can distinguish data signals from noise due to differences in frequency, burst length, and envelope duty cycle. The data signal should be close to the device’s band-pass center frequency (e.g. 38 kHz) and fulfill the conditions in the table below.
When a data signal is applied to the product in the presence of a disturbance, 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 which are suppressed are:
• DC light (e.g. from tungsten bulbs sunlight)
• Continuous signals at any frequency
• Strongly or weakly modulated patterns from fluorescent lamps with electronic ballasts (see figure 14 or figure 15).
