A new mixed-mode binary phase shift keying (BFSK) demodulator is demonstrated using a half-rate bang-bang phase detector commonly used in clock and data recovery (CDR) applications. This demodulator can be used for new home networking applications using already installed CATV lines. A prototype chip realized by 0.18-μm CMOS process can demodulate 622-Mb/s data at 1.4-GHz carrier frequency. At this data rate, the demodulator core consumes 27.5 mW from a 1.8 V power supply while the core chip area is 210 × 150 μm 2. The transmission over 20-m CATV line using the prototype chip is successfully demonstrated.
