Clock Times HD Audio

The 10 MHz to 50 MHz CCHD-957 HCMOS clock oscillator with standby mode specifies a phase noise figure of -100 dBc/Hz at 10-Hz offset and a typical noise floor of -170 dBc/Hz at 100-kHz offset. The component targets audio applications such as DACs, ADCs, digital audio broadcasting, and professional CD equipment. Housed in a 9 mm x14 mm SMT package, it operates with a +3.3V power supply consuming 15 mA of current. Stability is rated at 20 to 50 ppm (0°C to +70°C) and ±25-50 ppm (-40°C to +85°C).
