TSOP12..KD1 Vishay Telefunken Photo Modules for PCM Remote Control Systems Available types for different carrier frequencies Type TSOP1230KD1 TSOP1236KD1 TSOP1238KD1 TSOP1256KD1 fo 30 k Hz 36 k Hz 38 k Hz 56 k Hz Type TSOP1233KD1 TSOP1237KD1 TSOP1240KD1 fo 33 k Hz 36.7 k Hz 40 k Hz Description The TSOP12..KD1 - series are miniaturized receivers for infrared remote control systems. PIN diode and preamplifier are assembled on lead frame, the epoxy package is designed as IR filter. The demodulated output signal can directly be decoded by a microprocessor. The main benefit is the reliable function even in disturbed ambient and the protection against uncontrolled output pulses. Features D Photo detector and preamplifier in one package D Internal filter for PCM frequency D Improved shielding against electrical field disturbance Special Features D Enhanced immunity against all kinds of disturbance light D No occurrence of disturbance pulses at the output TTL and CMOS patibility Output active low Low power consumption Suitable burst length ≥10 cycles/burst Block Diagram 2 Input Control Circuit 80 k W 3 PIN AGC Band Pass Demodulator 1 GND 94 8136 Document Number 82126 Rev. 4, 30-Mar-01 .vishay. 1 (7) TSOP12..KD1 Vishay Telefunken...
