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 outputs. The counters are programmed via a synchronous serial port which is SPI compatible.
