Ultrahigh-Speed (100 MHz) Photodetector IC for CD-ROM and DVD-ROM Players

Sony has created a photodetector IC product for use as the optical pickup in CD-ROM and other optical disc drives. This device (the CXA2586M) achieves the industry’s highest performance: a bandwidth of 100 MHz.
The CXA2586M supports CD-ROM drives with read speeds of 60× or higher and DVD-ROM drives with read speeds of up to 12×.
A newly developed ultrahigh-speed photo IC process (P-42B) was adopted, allowing the CXA2586M not only to achieve higher speeds, but also to achieve a noise level reduced by –6 dB from conventional products.

■ Ultrahigh speed: 100 MHz
■ Low noise: –87 dBm (@54 MHz)
■ On-chip summing amplifier
■ Miniature transparent molded package (SOP)
