SP5658 Datasheet 2.7ghz 3-wire Bus Controlled Frequency Synthesiser

Manufacturer: Mitel Networks

Overview: SP5658 2.7GHz 3-Wire Bus Controlled Frequency Synthesiser Advance Information Supersedes October 1996 Media IC Handbook HB3923-2 DS4064 - 4.1 March 1998 The SP5658 is a single chip frequency synthesiser designed for tuning systems up to 2.7GHz. The RF preamplifer contains a divide by two prescaler which can be disabled for applications up to 2GHz so enabling a step size equal to the parison frequency up to 2GHz and twice the parison frequency up to 2.7GHz. parison frequencies are obtained either from a crystal controlled on–chip oscillator or from an external source. The device contains two switching ports, in the 14 pin version and four in the 16 pin, together with an ‘‘in–lock” flag output. The device also contains a varactor line disable and charge pump disable facility.
