• DVD write channel maximum drive current: 270mA

• DVD total maximum drive current: 360mA

• 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/

• 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).
