The ML145159 is a programmable PLL frequency synthesizer designed by Lansdale Semiconductor, Inc. It features a 14-bit reference counter and programmable divide-by-N and divide-by-A counters, which can be configured serially through a common data input. This device operates within a supply voltage range of 3.0 to 9.0 V and has a wide operating temperature range of -40¬8C to 85¬8C. The synthesizer is compatible with the Serial Peripheral Interface (SPI) commonly used in CMOS microcontrollers, making it suitable for various applications. It supports a divide range of R from 3 to 16383 and N from 16 to 1023, with a phase detector that offers high gain. The ML145159 is designed for low power consumption due to its CMOS technology and can be used with both on-chip and off-chip reference oscillators. Engineers considering this product should note its maximum ratings, including a power dissipation limit of 500 mW and input/output voltage constraints. The device is also noted for its ability to interface with dual-modulus prescalers for higher frequency operations.
This family of CMOS PLL devices is designed to perform phase-locked loop functions and includes phase detectors, dividers, encoders, decoders, and oscillators, which use the lower power consumption of the CMOS process.
