cf5034 series nippon precision circuits inc.? 330mhz pecl-output oscillator ics overview the cf5034 series are differential lvpecl output oscillator ics. they are made using a bicmos process which allows high-frequency oscillator circuits and differential lvpecl output circuits to be fabricated on a single chip. two oscillator modes are supported?30mhz maximum fundamental oscillation mode, and 80mhz to 160mhz 3rd overtone oscillation mode. the cf5034 series devices require only the connection of a crystal to realize a differential lvpecl output oscillator circuit. features 3.3 ?0.3v operating supply voltage oscillator frequency range 80mhz to 330mhz fundamental oscillation mode 80mhz to 160mhz 3rd overtone oscillation mode 40mhz to 330mhz output frequency range differential lvpecl output f o (oscillator frequency) or f o /2 output frequency, determined by internal connection 50 ?5% output duty (measured at output crossing point) standby function: outputs are high impedance when oe is low. power-saving pull-up resistor built-in (pin oe) chip form (cf5034 ) series lineup ordering information version oscillation mode recommended oscillator frequency [mhz] 1 1. the recommended oscillator frequency criteria is based on the negative resistance characteristics and cutoff frequency. note that this may change depending on the crystal characteristics, thus suf?ient allowance should be made. output frequency cf5034aa fundamental 250 to 330 f o cf5034ab f o /2 cf5034ba 160 to 250 f o cf5034bb f o /2 cf5034da 80 to 330 (external capacitors required) f o cf5034db f o /2 cf5034la fundamental or 3rd overtone 125 to 160 f o cf5034lb f o /2 cf5034ma 80 to 125 f o cf5034mb f o /2 device package cf5034 ? 1 chip form
