FUJITSU SEMICONDUCTOR DATA SHEET DS06-80105-3E SEMI CUSTOM IF Band PLL Frequency Synthesizer MB15C100 Series s DESCRIPTION The Fujitsu MB15C100 series is an exclusive Intermediate Frequency (IF) band Phase Locked Loop (PLL) frequency synthesizer with pulse swallow operation. It can operate maximum at 500 MHz. The reference divider and comparison divider have fixed divide ratios, so that it is not required to set the divide ratios by a µcontroller externally. Because the dividers are designed .

FUJITSU SEMICONDUCTOR DATA SHEET DS06-80105-3E SEMI CUSTOM IF Band PLL Frequency Synthesizer MB15C100 Series s DESCRIPTION The Fujitsu MB15C100 series is an exclusive Intermediate Frequency (IF) band Phase Locked Loop (PLL) frequency synthesizer with pulse swallow operation. It can operate maximum at 500 MHz. The reference divider and comparison divider have fixed divide ratios, so that it is not required to set the divide ratios by a µcontroller externally. Because the dividers are designed by means of MASK ROM method, a customer can chose them optionally. SSOP-8 and BCC-16 plastic packages are available. All of the above features help a system designer for easier as well as compact layout work. It operates with a supply voltage of 3.0 V typ. and dissipates 1.2 mA typ. (@ 300 MHz) of current realized through the use of CMOS technology. s FEATURES • Operating frequency : 500 MHz max. • Low power supply current: ICC (total) = 1.2 mA typ. (VCC = 3V, 300 MHz) • Pulse swallow function; 500 MHz Prescaler: 8/9, 16/17, 32/33 • MASK ROM optional the comparison and reference dividers: - Main counter ; 5 to 4,095 - Swallow counter ; 0 to 31 - Reference counter ; 5 to 4,095 (Continued) s PACKAGES 8-pin plastic SSOP 16-pad plastic BCC (FPT-8P-M03) (LCC-16P-M06) MB15C100 Series (Continued) • Charge pump options: - L type ; Low sensitivity charge pump for direct modulation. (IOH/IOL = 1.5 mA @ VCC = 3.0 V) - H type ; Super charger circuit for High speed tuning. (IOH/IOL = 6.0 mA @ VCC = 3.0 V) • Low power supply voltage: VCC = 2.4 V min. • Wide operating temperature: Ta = –40 to +85°C • Selectable A or B type A: Div type Two different frequencies can be selected by Div input “H” or “L”. B: PS type Power saving control PS H L OSC Active Stop R Active Stop N. A. P Active Stop PS = “L” → Do = “Z”, LD = “H” • Plastic BCC-16 and 8-pin SSOP packages 2 MB15C100 Series s PIN ASSIGNMENT Divide ratio switching type (DIV) (TOP VIEW) VCC DO GND fin 1 2 3 4 8 7 6 5 OSCin LD fout DIV Power saving function type (PS) (TOP VIEW) VCC DO GND fin 1 2 3 4 8 7 6 5 OSCin LD fout PS (FPT-8P-M03) (FPT-8P-M03) (TOP VIEW) N.C. 16 N.C.
