• Description: Irda Compliant 4 Mb/s 3 V Infrared Transceiver - Agilent Hewlett-packard
• Manufacturer: Avago Technologies

Electrical & Optical Specifications
Specifications hold over the Recommended Operating Conditions unless otherwise noted. Unspecified test
conditions can be anywhere in their operating range. All typical values are at 25 C and 3.3 V unless
otherwise noted.
Notes :
15. Shields to be grounded.
10. For in-band signals
11. For in-band signals at 1.15 Mb/s where 9.0 W/cm
12. For in-band signals of 125 ns pulse width, 4 Mb/s, 4 PPM at recommended 400 mA drive current.
13. Pulse width specified is the pulse width of the second 500 kHz carrier pulse received in a data bit. The first 500 kHz carrier pulse
14. Wake up time is the time between the transition from a shutdown state to an active state and the time when the receiver is active
8. An in-band optical signal is a pulse/sequence where the peak wavelength, p, is defined as 850
9. Logic Low is a pulsed response. The condition is maintained for duration dependent on pattern and strength of the incident
