读通道和写通道
MAX9483/MAX9484
高性能、多模式
LDD
专为CD和
DVD
组合拾取头而设计。该驱动器具有三个电流通道。
每个通道有一个电流输入
IN_(_=1、2或3)
和一个通道控
制信号
(ENABLE、NE2或NE3)。IN1
为读通道提供基
准，这个通道为激光器提供读电流或偏置电流。另外两
个通道是写通道。这两个通道的电流叠加在读电流之
上， 在写模式下，读电流作为激光器的偏置电流使用。
偏置电流明显减少了激光器输出的上升时间。当
ENABLE
为低时，三个通道全部被禁用。将
ENABLE
拉
高，则读通道有效，而其他两个写通道由
NE2和NE3
控
制(请参见图1)。通过选择
IN2和IN3
的输入电流，以及
NE2和NE3
的信号时序，驱动器可产生满足不同
CD/
DVD
写标准的多种电流波形。所有三个通道的电流增益
都为
100
倍。每个输出能提供的最大总电流为
400mA
。
RF
振荡器
为降低读模式中的激光模式跳跃噪声， 利用频率为
100MHz至600MHz
的振荡器来调制读电流。外接一只电
阻，
R
F
，可确定振荡器频率。对于
MAX9484
，可外接两
只电阻，
R
F1
和
R
F2
，分别选择CD和
DVD
激光器的振
荡器频率。振荡电流的振幅由两只外接电阻，
R
S1
和
R
S2
，来设定，一只用于CD，另一只用于
DVD
。当
ENABLE和ENOSC
均被拉高时，振荡器有效。
