In the shut down mode, the PIN diode will be inactive and thus producing very little photo-current even under very bright ambient light. The HSDL–3600 also incorporated the capability for adjustable optical power. With two programming pins; MODE 0 and MODE 1, the optical power output can be adjusted lower when the nominal desired link distance is one-third or two-third of the full IrDA link. The HSDL-3600 comes in three package options; the front view option (HSDL-3600#007/#017), the front view guide pin option (HSDL-3600#107/#117), and the top view option (HSDL-3600#008/ #018). All options come with integrated shield that helps to ensure low EMI emission and high immunity to EMI field, thus enhancing reliable performance.

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 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-3600 has been shown to correctly receive all data bits for 9 µW/cm2 ≤ EI ≤ 500 mW/cm2 incoming signal strength. ASK 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. 15.

The temperature profile is divided into four process zones, each with different ∆T/∆time temperature change rates. The ∆T/∆time rates are detailed in the above table. The temperatures are measured at the component to printed circuit board connections. In process zone P1, the PC board and HSDL-3600 castellation I/O pins are heated to a temperature of 125°C to activate the flux in the solder paste. The temperature ramp up rate, R1, is limited to 4°C per second to allow for even heating of both the PC board and HSDL-3600 castellation I/O pins. 16 P3 SOLDER REFLOW P4 COOL DOWN ∆T 25°C to 125°C 125°C to 170°C 170°C to 230°C (245°C at 10 seconds max.) 230°C to 170°C 170°C to 25°C Process zone P2 should be of sufficient time duration (> 60 seconds) to dry the solder paste. The temperature is raised to a level just below the liquidus point of the solder, usually 170°C (338°F). Process zone P3 is the solder reflow zone. In zone P3, the temperature is quickly raised above the liquidus point of solder to 230°C (446°F) for optimum results. The dwell time above the liquidus point of solder should be between 15 and 90 seconds. It usually takes about 15 seconds to assure proper coalescing of the solder balls into liquid solder and the formation of good solder connections. Beyond a dwell time of 90 seconds, the intermetallic growth within the solder connections becomes excessive, ∆time Maximum ∆T/∆ 4°C/s 0.5°C/s 4°C/s - 4°C/s -3°C/s resulting in the formation of weak and unreliable connections. The temperature is then rapidly reduced to a point below the solidus temperature of the solder, usually 170°C (338°F), to allow the solder within the connections to freeze solid. Process zone P4 is the cool down after solder freeze. The cool down rate, R5, from the liquidus point of the solder to 25°C (77°F) should not exceed -3°C per second maximum. This limitation is necessary to allow the PC board and HSDL-3600 castellation I/O pins to change dimensions evenly, putting minimal stresses on the HSDL-3600 transceiver. Appendix A: Test Method A1. Background Light and Electromagnetic Field There are four ambient interference conditions in which the receiver is to operate correctly. The conditions are to be applied separately: 1. Electromagnetic field: 3 V/m maximum (please refer to IEC 801-3, severity level 3 for details). 2. Sunlight: 10 kilolux maximum at the optical port. This is simulated with an IR source having a peak wavelength within the range of 850 nm to 900 nm and a spectral width of less than 50 nm biased to provide 490 µW/cm2 (with no modulation) at the optical port. The light source faces the optical port. 3. Incandescent Lighting: 1000 lux maximum. This is produced with general service, tungsten-filament, gas-filled, inside frosted lamps in the 60 Watt to 100 Watt range to generate 1000 lux over the horizontal surface on which the equipment under test rests. The light sources are above the test area. The source is expected to have a filament temperature in the 2700 to 3050 Kelvin range and a spectral peak in the 850 to 1050 nm range. 4. Fluorescent Lighting: 1000 lux maximum. This is simulated with an IR source having a peak wavelength within the range of 850 nm to 900 nm and a spectral width of less than 50 nm biased and modulated to provide an optical square wave signal (0 µW/cm2 minimum and 0.3 µW/cm2 peak amplitude with 10% to 90% rise and fall times less than or equal to 100 ns) over the horizontal surface on which the equipment under test rests. The light sources are above the test area. The frequency of the optical signal is swept over the frequency range from 20 kHz to 200 kHz. Due to the variety of fluorescent lamps and the range of IR emissions, this condition is not expected to cover all circumstances. It will provide a common floor for IrDA operation. This simulates sunlight within the IrDA spectral range. The effect of longer wavelength radiation is covered by the incandescent condition. All Avago IR transceivers operating under the recommended drive conditions are classified as CENELEC EN60825-1 Accessible Emission Limit (AEL) Class 1. This standard is in effect in Europe as of January 1, 1997. AEL Class 1 LED devices are considered eye safe.

It is fully compliant to IrDA 1.1 specification up to 4 Mb/s, and supports HP-SIR, Sharp ASK, and TV Remote modes. The design of the HSDL3600 also includes the following unique features: • Low passive component count. • Adjustable Optical Power Management (full, 2/3, 1/3 power). • Shutdown mode for low power consumption requirement. • Single-receive output for all data rates. Adjustable Optical Power Management The HSDL-3600 transmitter offers useradjustable optical power levels. The use of two logic-level modeselect input pins, MODE 0 and MODE 1, offers shutdown mode as well as three transmit power levels as shown in the Table below. The power levels are setup to correspond nominally to maximum, two-third, and onethird of the transmission distance. This unique feature allows lower optical power to be transmitted at shorter link distances to reduce power consumption. 29 MODE 1 0 0 1 MODE 1 0 0 1 1 Transmitter Shutdown Full Power 2/ Power 3 1/ Power 3 There are 2 basic means to adjust the optical power of the HSDL-3600: 250 mW/sr of intensity at the recommended minimum peak pulse LED current of 400 mA. Dynamic: This implementation enables the transceiver pair to adjust their transmitter power according to the link distance. However, this requires the IrDA protocol stack (mainly the IrLAP layer) to be modified. Please contact Hewlett Packard Application group for further details. Interface to Recommended I/O Chips The HSDL-3600’s TXD data input is buffered to allow for CMOS drive levels. No peaking circuit or capacitor is required. Static: Pre-program the ROM BIOS of the system (e.g. notebook PC, digital camera, cell phones, or PDA) to allow the end user to select the desired optical power during the system setup stage. Selection of Resistor R1 Resistor R1 should be selected to provide the appropriate peak pulse LED current over different ranges of Vcc. The recommended R1 for the voltage range of 2.7 V to 3.3 V is 2.2 Ω while for 3.0 V to 3.6 V is 2.7 Ω. The HSDL-3600 typically provides Data rate from 9.6 kb/s up to 4 Mb/s is available at the RXD pin. The FIR_SEL pin selects the data rate that is receivable through RXD. Data rates up to 115.2 kb/s can be received if FIR_SEL is set to logic low. Data rates up to 4 Mb/s can be received if FIR_SEL is set to logic high. Software driver is necessary to program the FIR_SEL to low or high at a given data rate. 4 Mb/s IR link distance of greater than 1.5 meters have been demonstrated using typical HSDL-3600 units with National Semiconductor’s PC87109 3 V Endec and Super I/Os, and the SMC Super I/O chips.

Test Procedures 1. Two PC97338VJG evaluation boards were connected to the ISA Bus of two PCs (Pentium 200 MHz) running Microsoft’s DOS operating system. One system with an HSDL-3600 IR transceiver connected to the PC97338VJG evaluation board will act as the master device. Another system with an HSDL-3600 IR transceiver connected to the PC97338VJG will act as the slave device (i.e. Device Under Test). 2. The test software used in this interoperability test is provided by National Semiconductor. A file size of 1.7M byte from the master device, with the PC97338VJG performing the framing, encoding is transmitted to the slave device. The slave device, Functional Block Diagram with the PC97338VJG performing the decoding, and CRC checksum, will receive the file. The file is then checked for error by comparing the received file with the original file using the DOS “fc” command. 3. The link distance is measured by adjusting the distance between the master and slave for errorless data communications.
