The Magpies were able to fend off interest in their French midfielder over the summer, with Arsenal having moved for his services.
Cabaye's head was turned by the attention from Emirates Stadium and his future on Tyneside became shrouded in uncertainty.
He was welcomed back into the Newcastle fold, though, and remains a key performer in their engine room.
Cabaye was among the goals again on Saturday as he bagged a brace in a 3-1 victory at West Ham United and Pardew hopes no tempting offers will be tabled before the end of January.
He said: "All the transfer windows as manager of Newcastle are nervy and I will be nervous until it closes.
"Everybody is for sale at some price, but we're conscious that we have a good team and we will try to keep it together."
On Cabaye's showing at Upton Park, Pardew added: "Yohan has almost a free role in the No. 10 shirt and he has enjoyed that.
"He has added goals to his game. The first one was a class individual goal - the touch and the way he moved and the sublime moment he took to finish it.
"He was a class act all day. He has been a big player for us and it has helped us get a nice rhythm in midfield."
