(rl = 50 w to vdd -2.0v) rise/fall times: 1.5ns typical (20% vdd to 80% vdd) current consumption (15pf load): <24mhz: 25ma max. 24.01 to 96mhz: 65ma max. 96.01 to 700mhz: 100ma max. load: 50 w into vdd-2.0v start-up time: 5ms typ., 10ms max. duty cycle: 50%5% (at vdd -1.3v) input static discharge prot: 2kv min. storage temperature range: -55c to +150c ageing: 3ppm per year max., 2ppm thereafter. at t amb +25c enable/disable no connection: both outputs enabled disable: both outputs are disabled when control pad is taken below 0.3v referenced to ground. oscillator is always 'on'. (special request - oscillator is off when disabled.) enable: both outputs are enabled when control pad is taken above 0.7 vcc referenced to ground. absolute maximum ratings ( permanent damage may be caused if operated beyond these limits. ) supply voltage vdd: +4.6v max. input voltage vi: vss -0.5 min., vdd +0.5v max. input voltage vo: vss -0.5 min., vdd +0.5v max. specification part numbers hpw576 oscillator part numbers are derived as follows: example: 3hpw5762-a-250.000 hpw576 pecl oscillators supply voltage 3 = 3.3vdc series designation package style 5761 or 5762 stability code (see table) frequency stability over temperature range stability temperature range order code ppm c 25 -10 to +70 a 50 -10 to +70 b 100 -10 to +70 c 25 -40 to +85 d 50 -40 to +85 e 100 -40 to +85 f offset 10hz -65 100hz -95 1khz -120 10khz -125 100khz -121 1mhz -120 10mhz -140 dbc/hz phase noise (155.250mhz) jitter integrated phase jitter: 2.6ps typical at 155.520mhz (12khz to 20mhz) period jitter (rms): 4.3ps typical at 155.520mhz period jitter (peak to peak): 27ps typical at 155.520mhz 7 x 5 x 1.8mm 6 pad smd 750khz to 800.0mhz
