VOLTAGE CONTROLLED CRYSTAL OSCILLATOR - VCXO QEV 51-KO & QEV 51-KH TIME &FREQUENCY CONSUMER & INDUSTRIAL THROUGH HOLE VCXO Description Our QEV51-KO is a sinewave Voltage Controlled Crystal Oscillator in a package 20 x 20 x 10 mm which is designed for industrial temperature range of -40° C to +85° C with a sinusoidal output. It allows an upper frequency of 200 MHz by using an overtone quartz resonator in a sealed package and a pulling range up to ±100 ppm. This type of product is well suited for very low phase noise applications (typically -120 dBc/Hz @ 100 Hz and typically -155 dBc/Hz @ 10 kHz for F= 150 MHz). Using ACMOS technology, the QEV51-KH offers the same performance up to 120 MHz. Frequency range Minimum ordering information requirement (See Table 1 for available combinations) (See page 4-37 for package drawing) 14 MHz to 200 MHz Applications Example: QEV 51 - KO 155.52 MHz 100LQ15 Telecommunication system SONET / SDH / ATM Multiplexing Digital switching Phase locking Features Temperature ranges: up to -40° C to +85° C Frequency stability: ±15 to ±50 ppm Calibration (@25° C ± 2° C): ± 10 ppm Supply voltage: +5 V ± 5 % Current consumption: 35 to 50 mA Load (KH version): 15pF/10NTTL-gates Load (KO version): 0 dBm / 50 Ω Sub-harmonics (KO version): > -25 dBc Spurious (KO version): > -80 dBc Rise / fall time (KH version): 5 ns Ageing: ±3 ppm / 1st year Pulling range: >±50 ppm to ±100 ppm min. @ 2.5 Vdc ± 2 Vdc, slope positive Duty cycle: 50/50 ± 20 % Stability vs. power supply and load: ± 5 ppm Table 1: Other temperature ranges and stability available Frequency range Temperature range Control voltage @2.5V,Z>10 KΩ) Pulling range (positive slope) Output signal KO = Sinus KH = AHCMOS Pulling range ± 50 ppm ± 75 ppm ± 100 ppm (2) Temperature LQ = 0° C ~ +70 ° C HQ = -20° C ~ +70° C DT = -40° C ~ +85° C* Stability 15 = ± 15 ppm * 25 = ± 25 ppm 50 = ± 50 ppm Note: 1.
