Dual Serial Input PLL Frequency Synthesizer
On-Chip 1.1 GHz Prescaler
MB15U10
s DESCRIPTION
The Fujitsu MB15U10 is a dual serial input phase-locked loop (PLL) frequency synthesizer and is ideally suitable for mobile communications such as cellular phones. The MB15U10 has two PLL frequency synthesizer circuits on a single chip: one for transmission and the other for reception (PLL1 and PLL2). It can operate from a +2.6V to 5.5V supply. Fujitsu's advanced technology achieves an Icc of 7 mA (typical) as well as 10 A (max.) at power saving mode.
s FEATURES
* * * * Two PLLs' for transmission/reception Low current consumption : ICC = 7 mA typ. at 3 V Power saving function : IPS = 10 A max. Divide ratio setting with serial data input : Binary 12-bit reference counter:6 to 4,095 Binary 17-bit main counter: 1,024 to 131,071 *Main counters can be programmed individually each other. On-chip constant current source charge pumps Adjustable charge pump output current with an external resistor Lock detection function Phase matching circuit helps fast intermittent operation Plastic 20-pin SSOP (shrink small outline) package

s FUNCTIONAL DESCRIPTIONS
Serial Data Input
Serial data is processed using the Data, Clock, and LE pins. Serial data controls the programmable reference divider, programmable divider (PLL1) and programmable divider (PLL2) separately by means of address setting. Binary serial data is entered via the Data pin. One bit of data is shifted into the internal shift register on the rising edge of the clock. When the load enable pin is high, stored data is latched. a) Serial data input format
