5-Channel 2-LD Driver for Optical Disc Drive Description The CXA2697ER is a laser driver IC corresponded to DVD ×12 and capable of driving two high output lasers (CD/DVD) for writable optical discs. Features - CD write channel maximum drive current: 300m A (VCC = 3V, VCC_LD = 4.5V, VOP = 2.5V) - CD total maximum drive current: 370m A (VCC = 3.3V, VCC_LD = 5V, VOP = 2.5V) - DVD write channel maximum drive current: 270m A (VCC = 3V, VCC_LD = 4.5V, VOP = 3V) - DVD total maximum drive current: 360m A (VCC = 3.3V, VCC_LD = 5V, VOP = 3V) - Capable of generating five-value recording waveform through control of five channels - Rise/Fall times = 1ns - Read Channel: ×125 - Write Channel: ×470 - Read Channel has extensive low-noise design 1.5n A/√Hz (@20MHz, ILD = 35m A, Imod = 20m Ap-p) - High frequency modulator circuit - Frequency variable range: 200 to 600MHz - Modulator amplitude can be set separately for CD and DVD. - DVD modulator amplitude switching function - Timing input for generating recording waveform can be adapted to both differential input (LVDS) and single-end input (3.3V CMOS/TTL). Applications CD-R, CD-RW, DVD-R, DVD-RW, DVD+R/RW, DVD-ROM and DVD-RAM for high-speed writable optical disc drives Structure Bi-CMOS IC Preliminary 32 pin VQFN...
