Serial-Input PLL Frequency

Synthesizer

Interfaces with Single–Modulus Prescalers

The MC145155–2 is programmed by a clocked, serial input, 16–bit data

stream. The device features consist of a reference oscillator, selectable–refer-

ence divider, digital–phase detector, 14–bit programmable divide–by–N

counter, and the necessary shift register and latch circuitry for accepting serial

input data.

The MC145155–2 is an improved–performance drop–in replacement for the

MC145155–1. Power consumption has decreased and ESD and latch–up

performance have improved.

• Operating Temperature Range: – 40 to 85°C

• Low Power Consumption Through Use of CMOS Technology

• 3.0 to 9.0 V Supply Range

• On– or Off–Chip Reference Oscillator Operation with Buffered Output

• Compatible with the Serial Peripheral Interface (SPI) on CMOS MCUs

• Lock Detect Signal

• Two Open–Drain Switch Outputs

• 8 User–Selectable ÷ R Values: 16, 512, 1024, 2048, 3668, 4096, 6144,

8192

• Single Modulus/Serial Programming

• ÷ N Range = 3 to 16383

• “Linearized” Digital Phase Detector Enhances Transfer Function Linearity

• Two Error Signal Options: Single–Ended (Three–State) or Double–Ended

• Chip Complexity: 6504 FETs or 1626 Equivalent Gates
