MB15A01
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 programmable counter). The LSI is housed in a 16-pin or 20-pin SSOP package, contributing to space saving of the system incorporating it. In addition, the MB15A01 operates at a low supply voltage of 3.0 V (typical), achieving low current consumption (typically ICC = 6.5 m A) s FEATURES
