It is good for multiple light sources application, such as laser based projectors. ISL58328 has two banks of three sets of gain registers. For a Pico-Projector application, the two banks of gain resistors can be used to monitor bias level and peak level of each wavelength. Bank switching is done by applying a TTL compatible logic signal to HL pin. The three sets of gain registers can be used to adjust optical-to-electrical conversion gain for each RED, GREEN, and BLUE laser or any wavelength in a spectral range for application. The ISL58328 is a single die device that has a photo detector of 0.7mm diameter in the center of the die. Photo current signal is amplified through TIA, fine gain amplifier, and output drivers to convert from current to voltage. The output of ISL58328 can be configured to be either differential or single-ended. Gain changing according to each wavelength is done through 3-wire interface. Registers can be updated in real time while the device is in operation. • High Sensitivity from 400nm to 1000nm with Patented Technology for Improved Blue Photo Response The ISL58328 operates from a single +5.0V supply. It is available in a space-saving 9 ball glass top BGA package.

It is sensitive from 400nm to 1000nm for light monitoring application, which is a perfect choice for Light Automatic Power control. This wide range of sensitivity also allows the ISL58328 to be used for white balance control in LED systems such as LED based LCoS or DLP pico projectors. Current generated by the photo detector, is amplified by a trans-impedance amplifier (TIA). The TIA has four feedback resistors. Users can choose which feedback resistor is used for HIGH or LOW gain applications by setting the tia_gain register. Once a proper resistor is selected for the required TIA gain, optical signal is then amplified by the TIA that feeds into the fine gain stage. HIGH gain channel and LOW gain channel TIA gains can be individually set through the TIA register. The HIGH gain and LOW gain channels have the same gain adjustment range (25dB) and can be individually controlled. In applications where laser power is modulated between 2 power levels, users can choose between HIGH gain channel for the low power level and LOW gain channel for the high power. It can provide the best resolution when power is low and not saturate the amplifier circuit when power is high. If users don’t need to monitor two power levels, there is no need to switch between HIGH gain channel and LOW gain channel.The selection of HIGH gain or LOW gain signal path can be done with fast hardware switching or by setting register bit “h/l”. When changing HIGH Gain or LOW Gain signal paths by hardware switching, “h/l” bit (Reg 0x10 bit [7]) needs to be “1”. When changing it with register (soft switching), HL pin needs to be driven by digital HIGH because HL and “h/l” are AND for TIA gain control. Regardless of channel gain settings, the dynamic range of TIA is determined by the photo detector sensitivity with respect to wavelength. For example in 445nm application when TIA = 01b gain is selected, the maximum input optical power is limited to 2mW for blue light laser; but this limitation is reduced to 1.45mW with 638nm laser. This is because the photo detector has higher optical-to-electrical conversion efficiency to longer wavelength. Higher than the maximum input limitation, the TIA or whole device will still be working but it may yield distorted output and a long fall time, increasing the time that the circuit used to recover from saturation.

Each wavelength has two 12-bit gain registers, one for HIGH gain application and the other for LOW gain application. The selection of HIGH gain or LOW Gain is done by fast hardware switching through HL pin or “h/l” register bit. All gain registers of HIGH Gain and LOW Gain channels are capable of update at anytime through the serial interface. The 12-bit gain registers provides total 25dB of adjustment range, +19dB to 5.5dB reference to fine gain setting 7FFh. All settings will be reset to default at power-on. Users need to load gain settings after ISL58328 is powered up. Overall differential output signal gain can be obtained by using Equations 1 through 3: Blue Laser Diode(445nm) 1.88 TIA Gain (mV/W = ------------------------------256 + Code (EQ. 1) Red Laser Diode (638nm) 2.57 TIA Gain (mV/W = ------------------------------256 + Code (EQ. 2) Green Laser Diode(530nm) 1.76 TIA Gain (mV/W = ------------------------------256 + Code (EQ. 3) Where: Code is 12 bits gain code in decimal (0 ~ 4095) TABLE 2. 7 tia_h, tia_l SETTINGS TIA FACTOR IN EQUATION 00b 500 01b 1000 10b 2000 11b 5400 FN6329.2 July 29, 2013 ISL58328 Output Configuration The ISL58328 has two differential outputs: OUTP is a positive and OUTN is a negative swing output. OUTP and OUTN outputs are referenced to VREF. VREF can be externally supplied or internally generated 2.1V. With respect to the input optical signal, OUTP swings up from reference voltage and OUTN swings down from reference voltage. Both OUTP and OUTN have the same linear output dynamic range up to 1.4V swing from reference voltage. When using external reference voltage, users need to adjust gain registers to set proper channel gain to prevent output saturation. To use ISL58328 as a single-ended output, users can take either OUTP or OUTN signal and load another output with equivalent resistor and capacitor load to keep both outputs with the same load condition. However, it won’t be an issue to leave another output floating. When using ISL58328 as a single-ended output device, external reference voltage is necessary because the VREF pin doesn’t have strong driving capability. It is not recommended to use VREF as a reference source to drive other devices. To obtain the best signal quality at the input of the AFE or video processor, it is recommended to keep OUTP and OUTN traces in parallel and to keep them with same length, same width, and route. If output signals from ISL58328 need to travel through a flex cable to AFE or video processor, to match with the impedance of flex cable, a 50 serial termination resistor close to OUTP and OUTN output pins may be necessary; thus the best value should be determined according to the actual application. Slow Tail Compensation Photons at longer wavelength will penetrate deeper into the photo detector structure than shorter wavelengths. It takes longer for electron-hole pairs to become photo current and results in a longer tail for the pulse output, called slow tail. Longer wavelength light such as 638nm or IR has more visible slow tail effect than blue laser. To minimize the slow tail effect, ISL58328 has incorporated Intersil’s proprietary slow tail compensation technology. There are three registers for slow tail compensation adjustment for each wavelength (such as 638nm, 532nm, and 445nm). The slow tail compensation function is not OUTP limited to the specific wavelength listed previously; it is used in conjunction with the selected fine gain registers. Users can disable slow tail compensation by setting Bit 7 (MSB) of the register to “0”. This function can also be used to improve the quality of pulse output waveforms due to impedance mismatch from OEIC outputs to the flex connector. One example is to improve Tr/Tf or to minimize overshoot. Layout Consideration When using differential output, layout OUTP and OUTN traces next to each other and ground traces should be placed to other side of OUTP and OUTN traces. When using single-ended, layout reference trace needs to be next to output signal trace and layout a ground trace at the other side ofthe output. For best result, dual layer flex with signal on one side and ground plane on other side is a must. Reference Voltage The ISL58328 has a reference voltage generator intended to generate 2.1V reference voltage for all circuit blocks. Output is biased at internal reference voltage automatically when VREF pin is left floating. When a DC voltage is applied to VREF pin, OUTP and OUTN will be biased at external reference automatically. External reference is limited to a range from 1.5V to 2.5V. Using voltage outside of this range will yield distorted outputs. When using external reference voltage, good decoupling is very important to prevent noise coupling into VREF. A 0.1µF ceramic capacitor placed as close to VREF pin as possible is recommended to decouple VREF to ground. Power Supply Decoupling Due to the current being switched rapidly at OUTP and OUTN, it is important to ensure that the power supply is well decoupled to ground. During output switching, the VDD undergoes severe current transients, thus every effort should be made to decouple the VDD as close to the package as possible. Without proper power supply decoupling there could make poor rise/fall times, overshoot, and poor settling response. > 1V OFFSET < 50mV VREF = 2.1V OUTN >1V Above minimal of 1V, linearity is no longer guaranteed FIGURE 2.
