CXA2640ER Overview
The CXA2640ER is a laser driver IC capable of driving two high output lasers (CD/DVD) for writeable optical discs.
CXA2640ER Key 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 Maximum modulator current amplitude: 1
- Timing input for generating write waveform can be adapted to both differential input (LVDS/LVPECL) and single end input
- Single 5V power supply
