Choosing a crystal oscillator for an ADC

Thread Starter

Hey everyone,

I need an external oscillator to drive the MCLK of my adc (AD7761) requiring a frequency of 32.768 MHz with a low input of 0.7 V and high of 2.34 V ~ 3.6v.

I'm unsure of how to go about selecting the oscillator and haven't really found anything online detailing it(except for RF applications). Ideally I'd like to buy an "all-in-one" component that I just give a supply voltage and it oscillates, although I'm not sure of how accurate these crystals really need to be and what the general pitfalls are.

Thanks in advance for any help!
