4.0 Optical Pulse Response
Figure 6 - Typical Optical Eye Diagram Response*
* (Measured using Sanyo DL-7140-201S Infra Red Laser Mounted on ZLE40510 Application Board)
(I read = 50 mA, I write =125 mA, at 15 mm with 200 MHz PRBS Pattern)
Figure 6 illustrates the typical optical response measured with the ZL40510/14 mounted on the ZLE40510/14
application board driving a Sanyo DL-7140-201S Infra Red Laser. The test condition is driving a PRBS pattern at
200 MHz clock rate which is representative of a 16X DVD write pattern using Block Write Strategy with minimum
write pulse of 2T duration.
The Sanyo DL-7140-201S Infra Red Laser Diode On resistance is typically 3 Ohms which is representative of the
On resistance of the Latest generation 250 mW pulsed High Power Red Laser Diodes that are targeted at 16X and
8X DVD.
The pulse is measured stepping from a low level which is above the laser threshold thus avoiding the laser turn on
transient which can distort the measured response.
The ZL40510/14 exhibits excellent pulse response characteristics when used with the optimum interconnect.
