IMI145158

SERIAL PROGRAMMED PLL FREQUENCY SYNTHESIZER

Approved Product

Product Description

Product Features

The IMI145158 is a member of a family of phaselock

loop synthesizer ICs from International Microcircuits.

This part is a single PLL in a small package for low cost

VHF applications. The IMI145158 is programmed with

standard 3-wire serial lines: data, clock, and enable.

>145 MHz typical input frequency.

-160 dBc/Hz total phase detector noise floor.

No dead zone by design.

Two phase detector outputs:

Blocks in the IMI145158 include a dual modulus

feedback divider for control of an external dual modulus

•

Current mode charge pump

Differential logic

prescaler. Prescaler ratios up to 128:129.

Also

included are an “N” counter, reference divider, phase

detector, and charge pump. The reference divider is

programmable from 1 to 16383. Both divider inputs are

biased for high sensitivity to sinewave input signals, and

the reference divider input can be configured to operate

as a crystal oscillator if desired. A buffered reference

signal output is also provided. The phase detector is a

Type IV phase-frequency design, which has inherently

eliminated the “dead zone” crossover distortion. The

loop error signal is provided by both a single-ended

charge pump output and standard differential logic

outputs.

Unambiguous PLL acquisition.

3-line serial programming: data, clock, & enable.

Compatible with the SPI (Serial Peripheral

Interface) on CMOS MCUs.

10-bit N counter: Divider range = 1 to 1023.

7-bit A counter: Divider range = 0 to 127.

14-bit R counter: Divider range = 1 to 16383.

On- or off-chip reference oscillator operation.

Buffered & filtered ref output is provided.

16 Pin SOIC package

Performance improvements of the IMI145158 over

other single loop CMOS PLL devices are in the

operating bandwidth and phase detector noise floor.

With its extremely low phase noise floor and wider input

bandwidth, prescaler ratios can be minimized to allow

wide loop bandwidths for faster settling and lower phase

noise.
