Description
The CXA2640ER is a laser driver IC capable of driving two high output lasers (CD/DVD) for writeable optical discs.
Features
- CD maximum drive current: 300mA DVD maximum drive current: 250mA.
- Capable of generating three-value write waveform through control of one read channel and two write channels.
- Rise/Fall times = 1ns.
- Read Channel: ×100.
- Write Channel: ×840 (CD), ×400 (DVD).
- Read channel has extensive low-noise design 1.5nA/√Hz (@20MHz, ILD = 35mA, IMOD = 40mAp-p).
- Internal high frequency modulator circuit Frequency variable range: 200 to 600MHz Maximu.
