  • Forum Post: Re: CDCE62002 Clock: Use sinewave as REFCLK?

    Fritz
    Sid, the CDCM7005 is an excellent performing clock jitter cleaner but it requires an external VCXO, which adds cost to the system. For systems that only need to generate a clean reference clock from a crystal or systems that need a jitter cleaner but can tolerate jitter in the order of 1ps rms the...

    I am using HCSL drive (IDT 851010AYLFT) to drive CDCE62005. What is the proper termination for HCSL to CDCE62005 or the interface between the two chips? Thanks.

    On CDCE62005 datasheet page 39, the input buffer parallel termination resisor is 50 ohm. But on CDCE62002 datasheet page 26, the resistor is 5K. What is the reason using 50 or 5K for seemingly same UIB?

    So, the termination/bias scheme shoue be AC coupling, 10K_pu/10K_pd and 50 termination in this order, and close to CDCE62005 input. Can I use 100_pu/100_pd instead of 3 resistors?

    OK, the 50 ohm termination is before the AC cap, (Not after). And after the ac caps, only a 10K_pu/10K_pd for bias, no termination. Please comfirm my understanding is correct. Thanks. But for CDCE62002, there is no termination at the receiver (CDCE62005 has), is that a concern?

    Hi, this looks overall good, but requires a few modifications: 1. the AUX_IN/XTAL input stage incorporates AC coupling. You must replace C353 with a zero-Ohm. 2. The XTAL driving stage is a Colpit oscillator, which means you need to connect one side of the XTAL to GND. You should replace C098...

    We have a cdce65005 providing a relatively low jitter 1GHz output from a 25MHz input. However for a new PCB where space was more of an issue we selected the cdce62002. Having bought the EVM board we cannot get lock with a 25MHz input & VCO = 2000MHz. Table 3 in datasheet SCAS882D states this...
