MOTOROLA SEMICONDUCTOR TECHNICAL DATA Order this document by MC145220/D MC145220 Dual 1.
1 GHz PLL Frequency Synthesizer BiCMOS The MC145220 is a low–voltage, single–chip frequency synthesizer with serial interface capable of direct usage up to 1.
1 GHz.
The device 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 device 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 ...
