Hpdvd1135i PATA drive, who is manufacturer?

I have spent about 40 minutes using google and the CDF search and found nothing on the manufacturer or chipset in this drive model.
It is available for purchase where I am located but I want to know what it is first.
I have downloaded the spec sheet and pic from HP site and I suspect it is possibly a liteon but I would like to know which model.
Anyone have info or a link with info on this model?

It’s a Lite-On. Not sure which model, but it is a Lite-On. An iHAP322 or something like that.

Thanks negritude.
Yea, it looked like a recent LiteOn in the photos I downloaded, but the models come out so quickly it’s tough to figure out which exact model it is without buying and opening it up.
