General Description
The EL6241C is a combination read + 2 write level laser driver and IV amplifier, with an extra read + oscillator ROM channel for use in dual laser ‘combo’ drivers. A separate (amplitude and frequency) oscillator modulates the selected output for laser noise reduction during read or write. All these functions are provided in a 24-lead QSOP package.
