? ? ? ? CFPT9300 ------- smd temperature compensated crystal oscillator (pluto) ------- ------- a series of lead free surface mountable tcxo/tcvcxo for medium to high volume applications where small size (5 x 3.2 mm) and high performance are prerequisites. ------- product description ------- the CFPT9300 uses rakon's proprietary asic 'pluto?', a single chip oscillator and analogue compensation circuit, capable of sub 0.3ppm performance over an extented temperature range. its ability to function down to a supply voltage of 2.4v and low power consumption makes it particulary suitable for mobile applications. ------- applications communications other ------- features hcmos or clipped sinewave output stability 0.2ppm over -20/70c or 0.3ppm over -40/85c ------- specifications ----- 1.0 specification references line parameter description 1.1 model description CFPT9300 1.2 rohs compliant yes 1.3 package size 5.0 x 3.2 x 1.7 mm (see model drawing) ----- 2.0 frequency characteristics (all) line parameter test condition value unit 2.1 frequency range frequency range available (note 1 & 2) 1.25 to 52 mhz 2.2 frequency calibration initial calibration @ 25c 1 max ppm 2.3 frequency stability over temperature reference to (fmax + fmin)/2 0.2 to 2 ppm 2.4 temperature range operating temperature range over which temperature stability is measured -40 to 85 c 2.5 reflow shift measured 60 minutes after reflow 1 max ppm ----- 3.0 frequency characteristics (clipped sinewave) line parameter test condition value unit 3.1 supply voltage stability 5% variation, reference to frequency at nominal supply voltage, typical 0.1 ppm 3.2 load sensitivity 10% variation, reference to frequency at nominal load, typical 0.05 ppm ----- page 1
