We have developed a 5000 ppm spread spectrum Serializer/Deserializer (SerDes) physical layer (PHY) chip compliant with Serial AT Attachment (ATA). The chip was fabricated with a 0.15 /spl mu/m 1.5 V CMOS process and includes a self-running spread spectrum carrier generator to provide both transmit and receive block, a self-running phase interpolator to recover the +/-5000 ppm spread spectrum receive (RX) clock and data.
