1 / 7 page TSOP22..WE1 Vishay Telefunken 1 (7) Rev. 5, 30-Mar-01 www.vishay.com Document Number 82092 Photo Modules for PCM Remote Control Systems Available types for different carrier frequencies Type fo Type fo TSOP2230WE1 30 kHz TSOP2233WE1 33 kHz TSOP2236WE1 36 kHz TSOP2237WE1 36.7 kHz TSOP2238WE1 38 kHz TSOP2240WE1 40 kHz TSOP2256WE1 56 kHz Description The TSOP22..WE1 – 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. 16 080 Features D Photo detector and preamplifier in one package D Internal filter for PCM frequency D TTL and CMOS compatibility D Output active low D Improved shielding against electrical field disturbance D Suitable burst length ≥10 cycles/burst Special Features D Small size package D High immunity against disturbance light D No occurrence of disturbance pulses at the output D Short settling time after power on (<200ms) D Contiunous data transmission possible ( 800 bursts/s) Block Diagram 14318 PIN Input AGC Control Circuit Band Pass Demodu- lator 30 k W 3 2 1 VS OUT GND |
