DS04-21324-3E DATA SHEET ASSP for DTS Bi-CMOS 1.1 GHz PLL Frequency Synthesizer MB15A01 s DESCRIPTION The MB15A01 is a serial-input PLL (phase locked loop) frequency synthesizer LSI supporting a pulse swallow system. The LSI consists of: a 1.1 GHz band, dual-modulus prescaler allowing either of 64/65 and 128/129 frequency divisions to be selected, a control signal generator circuit, a 19-bit shift register, a 15-bit latch, a reference divider (binary 14bit reference counter), a 1-bit switch counter, a phase parator with phase conversion functions, a charge pump, a crystal oscillator, an 18-bit latch, and programmable dividers (binary 7-bit swallow counter and binary 11-bit...
