DGPS Beacon Receiver

I found an old design online and I have found suppliers for all of the parts except for one component, the MC145157 PLL Frequency synth. is hard to find. Lansdale Semiconductor now produces the chip and I need to find a supplier. Or buy it off of eBay for $30.

Current Status: Found the MC145157 chip
