De Jong arrived on Tyneside for a medical on Wednesday and is set to move to St James' Park from Borussia Monchengladbach until the end of the season with a permanent deal in the offing for this summer.
The Magpies tried to sign the Dutch international in 2012 while the 23-year-old was still with FC Twente and Pardew is pleased that the player will finally arrive at the club.
"He had a terrific spell in Holland, we were really keen on him at that moment," Pardew told Sky Sports following Newcastle's 0-0 draw at Norwich.
"He went to Germany and it has not quite worked out for him for whatever reason, so we are kind of giving him a chance.
"The platform for him is to come, play as well as he can and see if he can earn a contract here. He has got the credentials, he is a big target man with a good technique, he is the type of player our fans like."
Pardew was also hopeful that Newcastle director of football Joe Kinnear may be closing in on some other arrivals before the transfer window shuts on Friday.
"I will speak to Joe tomorrow, hopefully they have worked hard today and hopefully we will have some positive news when I wake up."
The stalemate at Carrow Road saw Newcastle hit the woodwork three times, but striker Loic Remy was sent off for aiming a head-butt towards Norwich's Bradley Johnson, who was also sent off for his reaction after an initial bout of shoving.
"They pushed each other, the arms are raised and the heads have met," Pardew added.
"There is enough there for them both to get sent off but Johnson, he should be really disappointed in himself for the way he reacted as if he had been head-butted. That was not on at all, I am surprised at him because I thought he was an honest pro.
"We should have won this with hitting the woodwork three times, but it's still a good point because this is a difficult place to come."
