    "content": "Hi Jim, et al.,\n\nThe 10 MHz oscillator I use is a voltage controlled (it could be phase \nlocked) temperature compensated crystal oscillator, the Taitien (a \nTaiwan company) Model TCCTDLSANL at $3.93 each in quantities 1 to 10 \npcs. Their web site (for ordering online) is \"t-mallusa.com.\"\n\n1. +/- 2.5 PPM stability (the test data supplied shows it did +/- 2PPM) \nover -40 to +85 (down to +/- 0.5 PPM available but at a much higher cost)\n\n2. +/- 0.5 PPM frequency accuracy at 25C\n\n3. 5V at 2mA\n\n4. 0.8 Vp-p clipped sinewave output into 10Kohm load\n\n5. 7x5x1.85mm ceramic SMD package\n\n6. Phase noise at 10Khz is -149 dBc/Hz (confirmed in the S2 concept \ndownconverter LO)\n\nDigikey and Mouser stock similar product but I'm very pleased with the \nperformance and service I get from these folks.\n\nSo there you have it...Bill - N6GHz\n\n\nJim Sanford wrote:\n> Bill:\n> Please share with ALL of us the info on the one you've settled on.
