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?
