DS4160D+

Programmable Timers And Oscillators Overview

The DS4160D+ is a ceramic surface-mount crystal oscillator from the Maxim DS4-XO series, manufactured by Analog Devices Inc./Maxim Integrated. It generates a nominal output frequency of 160MHz with an initial tolerance of ±20ppm and total frequency stability of ±50ppm over temperature. The device operates on a 3.3V supply (3.135V to 3.465V) and consumes approximately 52mA in LVDS mode. It features low phase jitter (<0.7ps RMS from 12kHz to 20MHz) and is housed in a compact 10-pin LCCC package measuring 5.0mm x 3.2mm x 1.49mm.

Programmable Timers And Oscillators Feature Summary

• Low Phase Jitter: Typical integrated phase jitter is less than 0.7ps RMS across 12kHz to 20MHz bandwidth.
• Dual Output Types: Available in LVDS configuration for the D+ suffix; supports differential signaling.
• Compact Package: Housed in a 10-pin Lead-Free/RoHS-compliant LCCC ceramic package (5.0mm x 3.2mm).
• Wide Operating Range: Designed for industrial temperatures ranging from -40°C to +85°C.

Programmable Timers And Oscillators Applications

• InfiniBand systems
• BPON/GPON networks
• Ethernet and 10GbE interfaces
• SONET/SDH equipment

Programmable Timers And Oscillators Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and lead finish specifications (JESD97 category e4). Check current lifecycle status as discontinuation notices may affect long-term availability.

Programmable Timers And Oscillators Selection Notes

Select the DS4160D+ specifically for LVDS output requirements at 160MHz. For LVPECL outputs, choose the DS4160P+ variant instead. Ensure PCB layout accommodates the 10-LCCC footprint and provides adequate thermal dissipation within the specified operating temperature range.

Programmable Timers And Oscillators Part Context

This component belongs to the DS4-XO series of crystal oscillators, which utilize fundamental-mode AT-cut crystals combined with PLL technology. The series includes various frequencies such as 125MHz, 155.52MHz, and 622.08MHz, all sharing similar packaging and electrical characteristics.

Programmable Timers And Oscillators Replacement Considerations

The DS4160P+ serves as the functional equivalent with LVPECL outputs. Other series members like DS4156D+ (156.25MHz) or DS4250D+ (250MHz) share the same package but differ in frequency.

Programmable Timers And Oscillators FAQ

What is the function of Pin 1?

Pin 1 is the Output Enable (OE) pin, which is active-high logic and includes an internal 100kΩ pullup resistor.

How should the exposed paddle be handled?

The exposed paddle (EP) must not be connected electrically, and no exposed metal should be placed under this pad location.

What are the unused pins?

Pins 2, 7, 8, 9, and 10 are No Connection (N.C.) and must be floated.
