Other Parts Discussed in Thread: LMX2581

Dear All,

I am going interface my board with TLK2711 EVM. Could anyone suggest the part no for GTX Clock with 110MHz and <20ps peak to peak jitter.

Thanks in avance.

Hi,

TI has a wide selection of clock solutions in our portfolio. I'd suggest to do online search and review them. Once such alternative is LMX2581.

Dear cordially,

Thanks for your reply. Could you please suggest the oscillator directly instead of using PLL. The recommended operating supply should be 2.5V asper the datasheet of TLK2711.

Thanks & Regards,

Hi,

The parts which you suggested all work with 3.3V logic level but the TLK2711 will work at a logic level of 2.5V. I want a frequency of 110MHz.

Could you please suggest the parts to be used.

Thanks & Regards,

C Ashok Reddy.

Hi,

It does appear like all of the TI clock oscillators are for 3.3V logic.

DigiKey has several 2.5V supply oscillators. You may use on of these.
