A PIN diode and a preamplifier are assembled on a lead frame, he epoxy package acs as an IR filer. The demodulaed oupu signal can be direcly decoded by a microprocessor. The TSOP382.., TSOP392.. are compaible wih all common IR remoe conrol daa formas. The TSOP384.., TSOP394.. are opimized o suppress almos all spurious pulses from energy saving fluorescen lamps bu will also suppress some daa signals. This componen has no been qualified according o auomoive specificaions.

5 SUITABLE DATA FORMAT These producs are designed o suppress spurious oupu pulses due o noise or disurbance signals. Daa and disurbance signals can be disinguished by he devices according o carrier frequency, burs lengh and envelope duy cycle. The daa signal should be close o he band-pass cener frequency (e.g. 38 khz) and fulfill he condiions in he able below. When a daa signal is applied o he IR receiver in he presence of a disurbance signal, he sensiiviy of he receiver is reduced o insure ha no spurious pulses are presen a he oupu. Some examples of disurbance signals which are suppressed are: DC ligh (e.g. from ungsen bulb or sunligh) Coninuous signals a any frequency Srongly or weakly modulaed noise from fluorescen lamps wih elecronic ballass (see figure 15 or figure 16) IR Signal Time (ms) Fig IR Signal from Fluorescen Lamp wih Low Modulaion IR Signal Time (ms) Fig IR Signal from Fluorescen Lamp wih High Modulaion TSOP382.., TSOP392..
