| FACTORY PROGRAMMED OSCILLATORS EQXOP-1000 SERIES 14 pin Dual-in-Line Programmable Oscillators DESCRIPTION The Euroquartz range of factory programmable oscillators provide custom frequency and specification oscillators within very short lead times. The parts are very reliable in use and have stabilities from 25ppm over -40 to 85C. In addition to the stability over operating temperature range customers may also choose from supply voltages of 2.7, 3.3 and 5.0 Volts, Enable/Disable or Power Down functions and output synchronous or asynchronous . OUTLINE & DIMENSIONS FEATURES * * * * * Very quick delivery available Industry-standard 14 pin DIL package (SMD version available) Frequency range 1MHz to 133MHz Supply Voltages 2.7 Volts, 3.3 Volts or 5.0 Volts Enable/Disable or Power Down options OPERATING LOAD CONDITIONS GENERAL SPECIFICATION Package Type: Frequency Range 5.0 Volt Supply: 3.3 Volt Supply: 2.7 Volt Supply: Frequency Stability*: 14 pin DIL Resistance-welded Maximum Capacitive Load TTL 5.0 Volt Supply 1.0MHz ~ 40MHz: 40.1MHz ~ 133MHz: 50pF 25pF 1.0MHz to 133.0MHz Maximum Capacitive Load CMOS 1.0MHz to 100.0MHz 5.0 Volt Supply 1.0MHz to 100.0MHz 1.0MHz ~ 66MHz: 50pF 25ppm to 100ppm 66.1MHz ~ 133MHz: 25pF (over operating temperature range) 3.3 Volt/2.7 Volt Supply Operating Temperature Range 1.0MHz ~ 40MHz: 30pF Choice of three ranges: 0 ~ +70C Part code: `C' 40.1MHz ~ 100MHz: 15pF -20 ~ +70C Part code: `D' -40 ~ +85C Part code: `I' PRODUCT SELECTION Storage Temperature Range: -55 to +125C Ageing: 5ppm/year maximum Frequency Operating (Ta=25C, Vdd=2.7V, 3.3V or 5.0V) Model Number Stability Temperature Packaging: Bulk pack or tubed (ppm) Range Output Levels: TTL or CMOS EQXOP-1100UC 100 0~+70 Maximum Output Loads EQXOP-1050UC 50 0~+70 <40MHz: 30pF (See note opposite) EQXOP-1025UC 25 0~+70 >40MHz: 15pF (See note opposite) EQXOP-1100UD 100 -20~+70 Duty Cycle EQXOP-1050UD 50 -20~+70 CMOS <40MHz: 45/55% maximum EQXOP-1025UD 25 -20~+70 CMOS >40MHz: 40/60% maximum EQXOP-1100UI 100 -40~+85 Output Clock Rise/Fall Times: 4ns maximum EQXOP-1050UI 50 -40~+85 Power Supply Current: 25mA (unloaded ) EQXOP-1025UI 25 -40~+85 Standby Current: 10mA typical 50mA maximum Start-up Time: Power Down Delay Time Synchronous: Asynchronous: Output Disable Time Synchronous: Asynchronous: Output Enable Time: RMS Jitter 1MHz~33MHz: 33MHz~133MHz: 10ms maximum (from power-on) T/2ns typical, T+10ns maximum 10ns typical, 15ns maximum T/2ns typical, T+10ns maximum 10ns typical, 15ns maximum (T = frequency period) 100ns maximum PART NUMBER GENERATION Frequency Nominal Frequency (MHz) EXAMPLE: Model No. See table above Supply Voltage Blank = 5.0 Volts A= 3.3 Volts B= 2.7 Volts Output Option T = Tristate (Enable/Disable P = Power Down 24.8920MHz EQXO-1050UDTA 50ps maximum 40ps maximum Frequency = 24.8920MHz, EQXOP-1000 package, 50ppm -20~+70C, Tristate, supply voltage 3.3 Volts * The frequency stability parameter is an inclusive figure and includes adjustment tolerance at 25C, stability over operating temperature range, variations due to load change 10%, supply voltage change 10%, first year ageing, shock and vibration. SYNCHRONOUS/ASYNCHRONOUS By default oscillators with Enable/Disable or Power Down functions are supplied ASYNCHRONOUS. If SYNCHRONOUS operation is required append `SYNC' to the part number EUROQUARTZ LIMITED Blacknell Lane CREWKERNE Somerset UK TA18 7HE Tel: +44 1460 230000 Fax: +44 1460 230001 email: info@euroquartz.co.uk web: www.euroquartz.co.uk |
