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-...
