The company's TSOP5700 IR receiver module features a data rate of up to 20Kbps and a controlling distance of up to 15m, making the device suitable for IR remote control or data transmission applications such as those found in STBs, game controllers, and wireless keyboards.

The surface-mount device combines a photo detector and a preamplifier into a 7.2-by-5.3-by-4mm package. It operates on a 455kHz carrier frequency and is suitable for multimedia applications with a demodulated output signal that can be decoded directly by a microprocessor.

It also features an AGC circuit to provide improved immunity against light-source disturbances, while an external metal shielding offers protection against EMI. The receiver module's epoxy package doubles as an IR filter while an internal band filter allows PCM frequency operation.

The TTL- and CMOS-compatible module operates from a 2.7V to 5.5V supply and is capable of receiving a high envelope duty cycle.
