(20% to 80% of lvds waveform) current consumption (15pf load): 38mhz to 100mhz: 45ma max. 100.01 to 320mhz: 60ma max. 320.01 to 640mhz: 70ma max. load: 50 w from each output start-up time: 5ms typ., 10ms max. duty cycle: 50%5% (at 1.5v) drive capability: 100 ohms between outputs 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: +4.6vdc 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 hdf576 oscillator part numbers are derived as follows: example: 3hdf5762-a-250.000 hdf576 lvds oscillators 7 x 5 x 1.8mm 6 pad smd supply voltage 25 = 2.5vdc 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 -62 100hz -92 1khz -120 10khz -132 100khz -128 1mhz -140 10mhz -150 dbc/hz phase noise (156.250mhz) typ. 0.4ps 0.5ps 3.0ps 5.0ps 20ps 30ps max. integrated phase jitter: (12khz to 20mhz) period jitter: (rms) period jitter: (peak to peak) jitter (156.520mhz) 38.0mhz to 640.0mhz
