CXA2697ER
5-Channel 2-LD Driver for Optical Disc Drive ^Preliminary
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.
32 pin VQFN (Plastic)
Features
• CD write channel maximum drive current: 300mA
(VCC = 3V, VCC_LD = 4.5V, VOP = 2.5V)
• CD total maximum drive current: 370mA
(VCC = 3.3V, VCC_LD = 5V, VOP = 2.5V)
• DVD write channel maximum drive current: 270mA
(VCC = 3V, VCC_LD = 4.5V, VOP = 3V)
• DVD total maximum drive current: 360mA
(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
1.5nA/√Hz (@20MHz, ILD = 35mA, Imod = 20mAp-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).
