DS1023S-200+

Overview

The DS1023S-200+ is an 8-bit programmable timing element manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single 5V supply (4.75V to 5.25V) and features a 2ns step size with a maximum delay of 510ns relative to the reference output. The device supports both parallel and serial programming modes, allowing flexible configuration as a delay line, pulse width modulator, or free-running oscillator. It is housed in a 16-pin SOIC package and functions within an operating temperature range of 0°C to +70°C.

Feature Summary

• Configurable as a delay line, pulse width modulator, or free-running oscillator
• Supports parallel or serial programming interfaces
• Includes an on-chip reference delay for accurate phase variation
• Guaranteed monotonicity across all programmed values

Applications

• Clock phase control applications requiring full period delays
• Pulse width modulation signal generation
• Free-running oscillator circuits
• Programmable timing elements in digital systems

Procurement Notes

Verify the component authenticity by checking the manufacturer markings against official datasheet specifications. Confirm the package type matches the required 16-pin SOIC form factor. Ensure the operating environment stays within the specified 0°C to +70°C temperature range. Validate that the power supply voltage remains between 4.75V and 5.25V for proper functionality.

Selection Notes

Select this model when a 2ns resolution is required for delay adjustments up to 510ns. Consider the DS1023S-100+ for finer 1ns steps or the DS1023S-500+ for longer delay ranges. Ensure the design accommodates the specific serial or parallel interface requirements. Verify that the application does not exceed the maximum input frequency limits defined in the datasheet.

Part Context

This component belongs to the DS1023 series of 8-bit programmable timing elements. It shares functional similarities with the DS1020 and DS1021 but offers enhanced features such as internal clock delay capabilities exceeding one full period. The series provides various step sizes to suit different timing precision needs across industrial and commercial applications.

Replacement Considerations

Direct substitutes include other variants within the DS1023 family, such as the DS1023S-100+ or DS1023S-500+, depending on required step size and delay range. Cross-referencing pin compatibility and electrical characteristics with the original datasheet is essential before implementation.
