Optical Pickup Chipset with CD/DVD Recording Photodetector IC (PDIC)

Supports High-Speed Writing to both CD and DVD Media

The signal processing required for DVD is far more com-

RF/Servo PDIC

plex than that for CD.

Supports high-speed CD/DVD write operations

Sony has now developed an optical pickup chipset, the

CXA2677GA and CXA2676GA, that is appropriate for this

complex signal processing.

These devices adopt a newly-developed LGA type small

trathin pickups.

low gain mode settings.

Small Package

The band limiter function used in write

mode provides an average value signal

with high precision.

The CXA2677GA is a photodetector IC

(PDIC) that was developed as the photo-

detector element for optical pickups used

in DVD R/RW drives. It features two

additional pins: WPP1 (A + B) and WPP2

(C + D). This allows the generation of the

WRF signal used in earlier (CXA2660N)

CD-R/RW systems with the WPP1 +

WPP2 signal and the detection of address

bit signal unique to DVD R/RW with the

WPP1 – WPP2 signal. Also, it adopts a

three-stage structure with a write mode

and two read modes with high gain and

To increase the number of pins while re-

taining the package dimensions (4.5 × 3.2

mm) of the earlier chip on board (COB)

package, Sony developed a new land grid

array (LGA) package that positions the

contacts in a two-dimensional array on the

reverse side of the package. This allows

these devices to provide increased func-

tionality without increasing the mounting

area. This package is optimal for devel-

oping ultrathin pickups, that is, pickups

for use in 9.5 mm ultrathin drives.

CXA2676GA

The CXA2676GA adopts a two-channel

structure to allow the power of the CD

laser and the DVD laser to be set individu-

ally. It achieves fast response characteris-

tics, namely a slew rate of 250 V/µs and a

settling time of 7 ns. These characteristics

are adequate to support write speeds of ×52

for CD-R and ×8 for DVD-R.

Despite our busy schedule, we are

confident that we succeeded in re-

sponding to our customers’ input

to the greatest extent possible in

the development of these new

products. Even though the design

period was short, we put careful

detailed attention into every single

element in these products. We are

sure our customers will be fully sat-

isfied. It’s good to be able to relax

again now that this project is done.
