SK-2900

CRYSTAL CLOCK OSCILLATORS Differential Positive ECL (DPECL) Data Sheet 0012F Rev. C SK-2900 Series Description The SK-2900 Series of quartz crystal oscillators provide DPECL Fast Edge compatible signals. This device is to operate using positive voltage and uses multiple ground pins for improved signal integrity. This device is intended to operate on positive voltage for PECL applications. Features Wide frequency range–250.0MHz to 500.0MHz User specified tolerance available Case at electrical ground Will withstand vapor phase temperatures of 253°C for 4 minutes maximum All metal, resistance weld, hermetically sealed package High shock resistance, to 1500g Low Jitter Overtone technology High Q Crystal actively tuned oscillator circuit Power supply decoupling internal Dual ground plane for added stability No internal PLL avoids cascading PLL problems High frequencies due to proprietary design Electrical Connection Pin 1 2 6 7 8 9 13 14 Connection VCC VEE Case VEE Case Output /Output VEE Case VEE Case Enable/Disable 357 Beloit Street, P.O.
