I am looking for some information on some parts I have. I would like the
specs on two different TOKO Helical filters. The first is a 2 pole device
with the part numbers arranged like this on the side:

		1814
		405
		611R

The second is a three pole device with the numbers:

		1814
		401
		617R

I called TOKO and got the latest catalog but these numbers do not appear in
it anywhere.

Also...
I have been looking at the Plessy data book for their SP5060 synthesizer.
According to the specs this is a fixed modulus, divide-by-256 PLL. It also
states that any frequency between 300Mhz to 2Ghz may be generated with a 
suitable reference frequency. The spec I don't understand is the Min Frequency
Reference is listed as 2 Mhz. This would only allow 512 Mhz to be the minimum
output, not 300Mhz. To get a 300Mhz output would require a reference of
1.171875Mhz . I am thinking they just rounded the minimum frequency spec up
to fit in the table nicely. Does anyone have experience with this part? Thanks.
