Vishay Semiconductors
Low Profile Fast Infrared Transceiver (FIR, 4 Mbit/s)
for IrDA® Applications with Low voltage Logic (1.8 V)
Description
The TFBS6712 is the smallest FIR transceiver avail-
able. It is a low profile and low-power IrDA trans-
ceiver. Compliant to IrDA’s Physical Layer speci-
fication, the TFBS6712 supports data transmission
rates from 9.6 kbit/s to 4 Mbit/s with a typical link dis-
tance of 50 cm. It also enables mobile phones and
PDAs to function as universal remote controls for tele-
visions, DVDs and other home appliances. The
TFBS6712 emitter covers a range of 6.5 meters with
common remote control receivers. Integrated within
the transceiver module is a PIN photodiode, an infra-
red emitter, and a low-power control IC. The
TFBS6712 can be completely shutdown, achieving
very low power consumption. This type is adapted to
20208
work with a low logic I/O voltage of 1.8 V. For opera-
tion with VCC as logic voltage base TFBS6711 is avail-
able with otherwise same performance.

Note: All timing data measured with 4 Mbit/s are measured using the IrDA® FIR transmission header. The data given here are valid 5 µs
after starting the preamble.
*) IrDA latency definition: Receiver Latency Allowance (milliseconds or microseconds) is the maximum time after a node ceases trans-
mitting before the node’s receiver recovers its specified sensitivity. During this period and also during the receiver start up time (after power
on or shut down) the RXD output may be in an undefined state.
**) IrDA sensitivity definition: Minimum Irradiance Ee In Angular Range, power per unit area. The receiver must meet the BER speci-
fication while the source is operating at the minimum intensity in angular range into the minimum half-angle range at the maximum Link
Length
***) Maximum Irradiance Ee In Angular Range, power per unit area. The optical power delivered to the detector by a source operating
at the maximum intensity in angular range at Minimum Link Length must not cause receiver overdrive distortion and possible related link
errors. If placed at the Active Output Interface reference plane of the transmitter, the receiver must meet its bit error ratio (BER) specifica-
tion.
