Hi colleagues,
we want to design a 802.11ad system and we have a discussion about the PLL in the receiver. I proposed a Costas Loop but my colleagues prefer a classic PLL with an crystal oscillator and frequency dividers and so on because this concept they know and they have never heard from Costas Loops. Therefore I am searching for examples, where Costas Loops are used in real products. Using google I found mostly block diagrams where a PLL is implemented, but no statement, what kind of PLL is used. I mean, a Costas Loop is actually also a PLL. Or not?
Can somebody cite me some real examples? Maybe with references? Does vendors use Costas Loops in GSM systems? DVB? UMTS? Something else?
Or has somebody a proposal for a more suitable PLL for a 802.11ad system?
Thank you!
