Front-end processor core for up to 64X speed CD-ROM drive in 0.35um CMOS

We have developed a front-end processor core that can be easily embedded into CD/DVD-ROM drive LSIs. Our new slice level feedback system and novel circuit techniques suitable for on-chip design enabled a 3.35mm², 64X-speed processor for CD-ROM drive. A test chip was implemented in 0.35µm CMOS. Experimental results show that performance exceeds the requirements for 48X and potentially for up to a 64X- speed CD-ROM drive system.
