DS4026

General Description

Features

The DS4026 is a temperature-compensated crystal

oscillator (TCXO) that provides ±±ppm ꢀreꢁuency sta-

bility over the -40°C to +85°C industrial temperature

range. Each device is ꢀactory calibrated over tempera-

ture to achieve the ±±ppm ꢀreꢁuency stability. Standard

ꢀreꢁuencies ꢀor the device include ±2.8, ±9.44, 20.0,

38.88, 40.0, and 5±.84MHz. Contact the ꢀactory ꢀor cus-

tom ꢀreꢁuencies.

♦

1ppm Frequency Accuracy Over -40°C to +85°C

♦ Standard Frequencies: 12.8, 19.44, 20.0, 38.88,

40.0, 51.84MHz

♦ Maximum 4.6ppm Deviation Over 10 Years

♦ Minimum 8ppm Digital Frequency Tuning

Through I²C Interface

The DS4026 provides excellent phase-noise characteris-

tics. The output is a push-pull CMOS sꢁuare wave with

symmetrical rise and ꢀall times. In addition, the DS4026 is

designed to provide a maximum ꢀreꢁuency deviation oꢀ

less than ±4.6ppm over ±0 years. The device also pro-

vides an I²C interꢀace to allow pushing and pulling oꢀ the

output ꢀreꢁuency by a minimum oꢀ ±±5ppm typical with

typical ±ppb resolution.

♦ Surface-Mount 16-Pin SO Package

♦ Pb Free/RoHS Compliant

Pin Configuration

TOP VIEW

The DS4026 implements a temperature-to-voltage con-

version with a nonlinear relationship. The output ꢀrom the

temperature-to-voltage converter is used to drive the volt-

age-controlled crystal oscillator to compensate ꢀor ꢀre-

ꢁuency change.

The device implements an on-chip temperature sensor

lookup table, and a digital-to-analog converter (DAC) to

adjust the ꢀreꢁuency. An I²C interꢀace used to communi-

cate with the DS4026 perꢀorms temperature readings and
