What's New   RFGlobalnet   www /go/rf   Search /go/rf   IC Function Selection Guide   Prescaler ICs       Function:   Provides an output signal at one nth the input frequency, where n is the division ratio (or modulus) of the prescaler. A prescaler is often used as part of a PLL to provide a low frequency signal that can be locked to a stable low frequency reference.     Products   IFD-53 series Prescalers The use of high speed analog silicon processing results in specialty prescalers with good phase noise performance and operation to 6 GHz in unusually small packaging.   1. IFD-53010: divide by 4 premium performance (6 GHz)   2. IFD-53110: divide by 4 reduced frequency (5 GHz)   System Solutions Prescalers are integrated into some HP chip set solutions   1. HPMX-5001: up converter / down converter chip for 1.5 - 2.5 GHz FHSS chip set includes a divide by 32/33.   2. HPMX-5002: IF /Demodulator chip for 1.5 - 2.5 GHz FHSS chip set includes a divide by 9/12/16 and a divide by 90/216.   Key Parameters     divide ratio, maximum operating frequency, sensitivity, phase noise
