Product Summary
The MC145220F is a low–voltage, single–chip frequency synthesizer with serial interface capable of direct usage up to 1.1 GHz. The MC145220F simultaneously supports two loops. The two on–chip dual–modulus prescalers may be independently programmed to divide by either 32/33 or 64/65. The MC145220F consists of two dual–modulus prescalers, two 6–stage A counters, two 12–stage N counters, two fully programmable 13–stage R (reference) counters, and two lock detectors. Four phase/frequency detectors are included: two with current source/sink outputs and two with double–ended outputs.
