The CXA2660N is a photodetector IC

(PDIC) that detects the light reflected from

the disc. This device provides pulse

response characteristics (see table 1) that

allow applications to achieve high-speed

write operations. One feature of this

device is that in addition to an RRF output

pin used for RD signal detection during

playback, it also provides a WRF output

pin used for laser power detection during

writing. To improve the FPC (flexible

printed circuit) transmission characteris-

tics, this device is provided with a limiter

function for amplitude limitation for each

servo signal. It is provided in a miniature

transparent 14-pin molded package (in

Optical Pickup Chipset Achieves the Industry’s Fastest CD-R/RW Write Speed

CXA2660N/CXA2663N

CXA2652EM/AEM/BEM

The increases in CD-R write speeds have been phenom-

enal and currently rival playback speeds.

Sony has now developed both a photodetector IC (PDIC)

that achieves the industry’s fastest write speed and an IC

that monitors the laser power during write operations by

taking maximum advantage of the process technologies

of which Sony is so proud.

These ICs, which provide the top performance level in

the industry, enable the implementation of CD-R/RW

optical pickups with the industry’s highest write speed.

We had to work around the clock

for each IC in this chip set to cre-

ate this truly “sleepless” optical

pickup chip set, which supports

the industry’s fastest CD-R drives.

We reviewed Sony’s previously

developed technologies down to

the last detail to achieve the high-

est speeds possible. I strongly rec-

ommend that you put this chipset

in your next product’s “laser spot-

light.”

both straight lead and surface mounting

versions) and has a structure that can with-

stand reflow soldering (under stipulated

conditions).

Like the CXA2660N, the CXA2663N is

a PDIC that detects light reflected from

the disc and provides pulse response

characteristics (see table 1) that allow

applications to achieve high-speed write

operations. This device inherits the gain

switching function from the CXA2636N

and CXA2637N, and can both prevent

output voltage saturation during high-

speed writing as well as prevent signal-

to-noise ratio degradation in playback

mode. This device is also provided in a

miniature transparent 14-pin molded pack-

age (in both straight lead and surface

mounting versions) and has a structure that

can withstand reflow soldering (under

stipulated conditions).

The CXA2652 Series products are photo-

detectors (front monitors) that are used to

monitor the laser power during write op-

erations. Since these devices include a

built-in I-V amplifier, they have a low

output impedance and provide a stable

output. They are provided in a 6-pin side

through hole miniature COB (chip-on-

board) package (3.2 mm 4.5 mm). A chip

capacitor (1005) is included within the

package making these devices optimal for

optical pickups, which have limited

mounting space.
