CVHD-575 Model 5×7.5 mm SMD, 3.3V, HCMOS 1 -9 Hz / c dB @ Hz 0 10 65 -1 z /H c dB r oo l F Model CVHD-575 is the industry’s lowest phase noise VCXO in a 5×7.5 mm package. Close-in phase noise is -90 dBc/Hz @ 10 Hz while its floor is at -165 dBc/Hz. This oscillator may be small in size but it packs a punch inside. Its output driver is capable of driving ±24mA. Applications include Digital Video DACs, ADCs for HD Audio Low Phase Signal Sources Test and Measurement CRYSTEK CORPORATION Rev: A Date: 14-Jul-2015 Page 1 of 2 12730 Commonwealth Drive • Fort Myers, Florida 33913 Phone: 239-561-3311 • 800-237-3061 Fax: 239-561-1025 • www.crystek.com CVHD-575 Model 5×7.5 mm SMD, 3.3V, HCMOS Frequency Range: 20 MHz to 52 MHz* Temperature Range: (Option M) (Option X) Storage: Input Voltage: Input Current: Output: Symmetry: Rise/Fall Time: Logic: 0°C to +70°C (standard) -20°C to +70°C -40°C to +85°C -45°C to 90°C 3.3V ±0.3V 15mA Typical, 25mA Max HCMOS 45/55% Max @ zero crossing point 2nsec Max @ 20% to 80% Vdd “0” = 10% Vdd Max “1” = 90% Vdd Min 15pF ±24mA Max Load: Output Current: Input: Modulation Bandwidth: >10kHz @ -3dB Input Impedance: 51 kΩ Control Voltage: 1.65V ±1.65V Tuning Sensitivity: +22ppm/V Typical Frequency Pulling: ±20ppm APR Min (Inclusive of frequency stability, calibration, and aging.)
