LMH6526
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 (780 nm) lasers.
Key Features
- Fast switching: Rise and fall times: 0.6/1.0 ns.
- Low Voltage Differential Signaling (LVDS) channels enable interface for the fast switching lines
- Low output current noise: 0.24 nA/
- Dual Output: Selectable by SELA/B pin (active HIGH) SELA = LMH6526 SELB = LMH6525
- Four independent current channels Gain of 300, 300 mA write channel Gain of 150, 150 mA low-noise read channel Two gain of 150, 150 mA write channels 600 mA minimum combined output current
- Integrated AC Coupled HFM Oscillator Selectable frequency and amplitude setting by external resistors 200 MHz to 600 MHz frequency range Amplitude to 100 mA peak-to-peak modulation
- Complete shutdown by ENABLE pin
- 5V single-supply operation
- Logic inputs TTL and CMOS compatible
- Space saving Leadless Leadframe Package (LLP ® -28)
