The Motorola MC145155-2 is a CMOS integrated circuit designed as an improved-performance drop-in replacement for the MC145155-1. It functions as a Serial-Input PLL Frequency Synthesizer that interfaces with single-modulus prescalers.
The device features a 16-bit data stream programming capability, allowing for a programmable divide-by-N counter range of +N = 3 to 16383. Key characteristics include low power consumption via CMOS technology, an operating supply voltage range of 3.0V to 9.0V, and compatibility with the Serial Peripheral Interface (SPI) found on CMOS microcontrollers.
| Supply Voltage Range | 3.0 to 9.0 V |
|---|---|
| +N Counter Range | 3 to 16383 |
| Chip Complexity (FETs) | 6504 FETs |
| Compatible Interface | SPI on CMOS MCUs |
It is an improved-performance drop-in replacement for the MC145155-1 with decreased power consumption and improved ESD and latch-up performance.
The device is programmed by a clocked, serial input, 16-bit data stream.
The device is available in Plastic DIP (P), SOG (DW), and PLCC (FN) packages.
