Can i use a quartz crystal as clock for this flip flop IC

[vinayakdabholkar]

The HEF4013B from nxp is a dual d flip flop IC. I want to give independent clocks at the two clock inputs. Is it possible to use normal quartz crystals for clock sources here ? if possible how is the crystal to be connected ?

Yes, but you will need an extra logic chip (typically an unbuffered inverter like the 74HCU04) to make the oscillator. A quartz crystal needs a little extra circuitry to make it function as an oscillator. See here:
