LMK4906 EVB, VCXO oscillator ref ?

vincent merelle

hello

On the LMK4906 EVB instruction, the shematics part number of the 122.88Mhz VCXO is CVHD-950-122.88. There are clearly six pin on this oscillator, but on the datasheet of the CVHD-950 as only 4 pins! (http://www.crystek.com/crystal/spec-sheets/vcxo/CVHD-950.pdf)

is there a error in the shematic reference ?

Thanks,

This is not an error in the schematic. The schematic symbol and footprint can accommodate 4-pin 9x14 mm oscillator models (single-ended output), such as CVHD-950, as well as 6-pin 9x14 mm models (differential outputs).

Alan

ok thanks,

Any chance you have the datasheet of the 6-pin version?
because I need to by a CVHD-950 at 100Mhz, and I can not find the reference of the differential one, and the reference written on the VCXO on the board didn't help me ( E25.000 GRC17ON).

Redards,

Vincent

Hi Vincent,

Here are a couple links to example datasheets for 6-pin oscillator models that fit the VCXO footprint on the EVM.
