I'm trying to find a real world (not discontinued) crystal for the TUSB2046B that meets the requirements listed in the specifications:
"A 6-MHz fundamental crystal that is parallel loaded, like the Fox Electronics – part number HC49U-6.00MHz 30\50\0-70\20, (Discontinued). Needs to have ±30 ppm at 25°C and ±50 ppm from 0°C to 70°C, a load capacitance (CL) of 20 pF, maximum shunt capacitance (Co) of 7 pF, and the maximum ESR of 50 Ω in order to insure enough negative resistance."
I'm not seeing much out there with this ESR at this frequency. Anyone have any recommendations?
Thanks, Kevin
