Description

The MB15U37SLBPFT is an electronic component model in the IC Chip category. It is a dual serial input phase-locked loop frequency synthesizer that provides two PLL frequency synthesizer circuits on a single chip, one for transmission and one for reception (PLL1 and PLL2). It operates from a supply voltage of +2.6V to 5.5V and has low current consumption, which makes it an ideal solution for mobile communication devices such as cellular phones. The advanced technology used in its manufacturing achieves an ICC of 7 mA (typical) and 10 µA (max.) at power-saving mode.

Specifications and features

• Two PLLs for transmission/reception
• Low current consumption: ICC = 7 mA typ. at 3V
• Power-saving function: IPS = 10 µA 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 to 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

Application Scenarios

The MB15U37SLBPFT is suitable for use in mobile communication devices such as cellular phones. It can also be used in other electronic devices that require low current consumption and high-frequency stability.
