| Manufacturer | National Semiconductor |
| Description | The LMH™6525/6526 is a laser diode driver for use in combination DVD/CD recordable and rewritable systems. The part contains two high-current outputs for reading and writing the DVD (650 nm) and CD (7... |
| Features |
a 150 mA read channel plus one 300 mA and two 150 mA write channels, which can be summed to allow a total output current of 600 mA or greater. The channel currents are set through four independent current inputs. An on-board High-Frequency Modulator (HFM) oscillator helps reduce low-frequency noise of the laser and is enabled by applying LVDS levels on the ENOSC pins for the LMH6525, while the LMH6526 is enabled by applying an asymmetrical signal on the ENOSC pin. The fully differential oscillator circuit minimizes supply line noise, easing FCC approval of the overall system. The SELA/B pin (a... |
