Telefunken TSOP7000 Datasheet

Vishay Telefunken

IR Receiver for High Data Rate PCM at 455kHz

Description

The TSOP7000 is a miniaturized receiver for infrared
remote control and IR data transmission. 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
operation with high data rates and long distances.

Recommendation for Suitable Data Formats

The circuit of the TSOP7000 is designed in that way that disturbance signals are identified and unwated output
pulses due to noise or disturbances are avoided. A bandpassfilter , an automatic gain control and an integrator
stage is used to suppress such disturbances. The distinguishing marks between data signal and disturbance
are carrier frequency, burst length and the envelope duty cycle.

The data signal should fullfill the following conditions:

D

The carrier frequency should be close to 455kHz.

D

The burstlength should be at least 22ms (10 cycles of the carrier signal) and shorter than 500ms.

D

The separation time between two consecutive bursts should be at least 26ms.

D

If the data bursts are longer than 500ms then the envelope duty cycle is limited to 25%.

D

The duty cycle of the carrier signal (455kHz) may be between 50% (1.1ms pulses) and 10% (0.2.µs pulses).
The longer duty cycle may help to save battery power.
