DS1073Z-60

Overview

The DS1073Z-60 is a fixed-frequency oscillator manufactured by Analog Devices Inc./Maxim Integrated, housed in an 8-pin SOIC package. It generates a precise 60.000 MHz output signal with no external components required for basic operation. The device operates on a 2.7V to 3.6V supply and features user-programmable internal dividers (1 to 513) and prescalers (1, 2, or 4). Key electrical specifications include a typical active supply current of 50 mA at industrial temperatures (-40°C to +85°C), a standby current of 0.8 µA in power-down mode, and a frequency accuracy of ±0.5% at 25°C.

Feature Summary

• Dual outputs: Main oscillator output (I/O) and reference output (OUT0)
• User-programmable via 1-Wire interface for frequency and mode configuration
• Supports internal oscillator, external clock, or crystal reference inputs
• Glitch-free synchronous output enable and power-down control

Applications

• Microcontroller system clock generation
• Real-time clock circuits
• Communication interface timing sources

Procurement Notes

Verify the specific suffix 'Z' indicates the commercial temperature range (0°C to +70°C) as per the datasheet table. Confirm that the device requires external programming hardware using the 1-Wire protocol before board production, as factory defaults may not match the target application frequency.

Selection Notes

Select the DS1073Z-60 when a fixed 60 MHz clock is required without external crystals. Ensure the design accommodates the 50 mA active current draw. For applications requiring switching between internal and external references, configure the PDN/SELX pin accordingly during programming.

Part Context

This component belongs to the DS1073 EconOscillator family, which includes variants for 100 MHz, 80 MHz, and 66.667 MHz. The 'Z' suffix denotes the SOIC package and commercial temperature rating, while 'M' denotes the DIP package. These devices replace discrete crystal and buffer combinations.

Replacement Considerations

Direct functional substitutes within the same family include DS1073Z-100, DS1073Z-80, and DS1073Z-66, provided the frequency difference is acceptable. Cross-manufacturer replacements require verifying voltage compatibility and pinout alignment.

FAQ

How is the programming mode entered?

Programming mode is initiated by powering up the device with a pull-up resistor connected between the I/O pin and VCC. This pulls the I/O pin high during power-on reset.

What is the function of the OUT0 pin?

OUT0 provides a buffered output of the master reference clock (internal or external). It is unaffected by the OE pin but is disabled during power-down if the EN0 bit is set to 0.

Can the device switch between internal and external clocks dynamically?

Yes, if the PDN bit is programmed to 0, the PDN/SELX pin acts as SELX, allowing glitch-free switching between the internal oscillator and an external reference based on the logic level applied.
