1 / 14 page  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 comparison frequency up to 2GHz and twice the comparison frequency up to 2.7GHz. Comparison 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. FEATURES s Complete 2.7GHz single chip system s Optimised for low phase noise s Selectable divide by two prescaler s Selectable reference division ratio s Charge pump disable s Varactor line disable s ‘In–lock’ flag s Two switching ports in 14 pin version s Four switching ports in 16 pin version s Pin compatible with SP5659 I 2 C bus low phase noise synthesiserPP s ESD protection (Normal ESD handling procedures should be observed) APPLICATIONS s SAT, TV, VCR and Cable tuning systems s Communications systems Fig. 1 Pin connections – top view 114 116 116 CRYSTAL CHARGE PUMP DISABLE ENABLE DATA CLOCK PORT P1/OC DRIVE V EE RF INPUT RF INPUT V CC LOCK PORT P0/OP MP14 MP16 CRYSTAL CHARGE PUMP DISABLE ENABLE DATA CLOCK PORT P3 PORT P2 DRIVE V EE RF INPUT RF INPUT V CC LOCK PORT P0/OP PORT P1/OC ORDERING INFORMATION SP5658F/KG/MP1S (Tubes, 14 lead SO) SP5658S/KG/MP2S (Tubes, 16 lead SO) SP5658F/KG/MP1T (Tape and Mounted) SP5658S/KG/MP2T (Tape and Mounted) SP5658 2.7GHz 3-Wire Bus Controlled Frequency Synthesiser Advance Information Supersedes October 1996 Media IC Handbook HB3923-2 DS4064 - 4.1 March 1998 |
