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 5 V unless otherwise

noted.

Notes :

8. An in-band optical signal is a pulse/sequence where the peak wavelength,

λp, is defined as 850 ≤ λp ≤ 900 nm, and the pulse

characteristics are compliant with the IrDA Serial Infrared Physical Layer Link Specification.

9. Logic Low is a pulsed response. The condition is maintained for duration dependent on pattern and strength of the incident

intensity.

10. For in-band signals

11. For in-band signals at 1.15 Mb/s where 9.0

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

may exceed 2

µs in width, which will not affect correct demodulation of the data stream. An ASK or DASK system using the

HSDL-3601 has been shown to correctly receive all data bits for 9

or DASK should use the FIR channel enabled.

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

and ready to receive infrared signals.
