Dear all,
Regarding on the Bang-Bang type and Linear type phase detector for Clock Data recovery application, which one is better?
It seem bang bang type got large jitter, but with inherent retime data output. Linear type phase detector have better jitter performance while it suffer from the data-clock skew which reduce the time margin.
Even in Razavi's half rate phase detector, one paper in 2001 adopt the linear type PD, at year 2003, another paper they adopt a Bang-Bang type half rate PD.
Both seems to serve same application 10Gbs CDR.
I am working on the 2GHz CDR, any suggestion?
Thanks in advance!
Raymond
