Dallas Semiconductor's DS1075 EconOscillator™ offers designers a programmable replacement for bulky

resonators and oscillators. A single-chip, fixed-frequency oscillator, the DS1075 can be programmed to

produce a set frequency between 27kHz and 100MHz.

A programmable EEPROM divider and prescaler is used to produce the desired output frequencies. These

values can either be pre-programmed at the factory or user-configured. The chip maintains a 1% accuracy

over the specified temperature and voltage ranges. No external components are required, so the DS1075

saves board space for other functions.

The DS1075X-M Crystal Replacement Module is an evaluation tool allowing the installation of the DS1075

EconOscillator in an existing 8-pin and 14-pin oscillator sockets. The DS1075X-M consists of a printed

circuit board containing a DS1075Z but with the footprint and pinout matching most standard oscillator

footprints. The DS1075X-M is available in 30MHz, 33.333MHz, 40MHz, and 50MHz. Special frequencies

are available on request. Contact Maxim Direct for free samples or further information. Supplies are limited

to the quantities at hand.

The DS1075K, an evaluation and programming kit for the DS1075, is also available for $99.

Description

1) The DS1075X-M makes prototyping and product evaluation easy

Use the module for quick and easy evaluation of the DS1075 EconOscillator in existing crystal-based

sockets.

2) Replacing an oscillator with an 8-pin DIP footprint

Saw off the lower part of the PC board, insert, and power-up your board.

3) Replacing a crystal oscillator with a 14-pin footprint

Remove the two center pins on the module (see diagram). Pins can be removed by desoldering or cutting

them off.

4) Output-enable function

The enable pin operates like most crystal oscillator enable functions. If your design does not require this

function, the enable pin on the DS1075X-M can be tied high on your system board, or you can hardwire it to

pin 8 on the DS1075X board.
