The part is available in two industry-standard packages, 7 x 5mm SMD and 5 x 3.2mm SMD. Low jitter <1.0ps phase jitter Wide frequency Range 10.0MHz to 1450MHz Very short delivery leadtimes Low supply current <16mA at 100MHz Supply voltage range 2.5V or 3.3Volts Tristate function to conserve power FEATURES Output Logic Type: LVDS Frequency Range: 10.0MHz to 1450MHz Load: Differential Power Supply Voltage: 2.5±5%VDC or +3.3±10%VDC Differential Output Voltage: (VDD) 175mV min., 350mV typical VDD Magnitude Change (DVDD): 50mV max. Offset Voltage (VOS): 1.25V typical VOS Magnitude Change (DVOS): 50mV max. Frequency Stability: ±50ppm over -40° to +85°C* Duty Cycle: 50%±2% Rise Time: 150ps minimum** Fall Time: 250ps maximum** Current Consumption @+2.5VDD 100.000MHz: 16mA 250.000MHz: 18mA 500.00MHz: 21mA 750.00MHz: 22mA 1GHz: 24mA 1.35GHz: 26mA Current Consumption @+3.3VDD 100.000MHz: 18mA 250.000MHz: 20mA 500.00MHz: 22mA 750.00MHz: 24mA 1GHz: 26mA 1.35GHz: 28mA Current with output disabled: 16mA typical Start-up Time: 10ms maximum Ageing: ±2ppm max., first year, ±10ppm max. over 10 years. OE Control on Pad 1 Enable: 0.7% VDD min., or no connection Disable: 0.3%VDD max., (high impedance). Output Enable Time: 200ns max. Output Disable Time: 50ns max. Phase Jitter r.m.s.: 0.6ps typical (12kHz to 20MHz) <100fs (1.875MHz to 20MHz) GENERAL SPECIFICATION QF Series LVDS Oscillators DESCRIPTION 10MHz to 1450MHz ('536' package displayed) Notes: Example: 25HDQF536E-100.00 PART NUMBERING Supply Voltage 25 = 2.5 Volts 3 = 3.3 Volts Series/Model 'HDQF' = QF series, LVDS output Package 536 = 5.0mm x 3.2mm 576 = 7.0mm x 5.0mm Temperature Stability 'E' = ±50ppm over -40° to +85°C Frequency in MHz Page 1 of 4 TEST CIRCUIT |
