Why do you need more than one chip? Why can't the PIC generate the 60 KHz signal by bit banging a couple of pins? I'm thinking of a 2 or 3 bit D/A with 2 or 3 more pins for the low power portion of the signal. 1 bit might be enough with a good external filter. I wonder what the range would be using 2 feet of wire for an antenna. Do you want to fix your neighbors clocks too? -- These are my opinions, not necessarily my employer's.
