GENERAL DESCRIPTION
NJW4702 is a laser diode driver for the operation of a grounded laser diode for CD-R and CD-RW drivers.
It includes three channels current amplifiers for three different optical power levels. Reference inputs are voltage input, and voltage control is possible without external resistors. An on-chip RF oscillator is provided to reduce laser mode noise during read mode. Oscillation frequency and oscillation amplitude are defined by two external resistors.
