) ATAPI CD-R/RW Encoder/Decoder OVERVIEW The CL-CR3470 and CL-CR3475 are single-chip, highperformance, highly integrated ATAPI interface devices for the CD-R/RW (CD-Recordable/CD-Rewritable) market.
The CL-CR3470/CR3475 integrates CD-ROM decoder, CIRC encoder, EFM modulation, ATIP decoder, buffer manager, and ATAPI interface logic.
In addition to its CD-Rewritable capability, the CL-CR3475 features a DVD port enabling drive manufacturers to develop a drive that reads DVD, CD-ROM, CD-R, and CD-RW.
The CL-CR3470/CR3475 supports up to 40x read and 10x record disc speeds, allowing customers to preserve all CD-R/E encode/decode electronics and ﬁrmware as the disc speed requirements increase.
All write methods are supported by the CL-CR3470/CR3475 disc-at-once, track-at-once, packet recording, and (cont.
