DS4622P+

Programmable Timers And Oscillators Overview

The DS4622P+ is a ceramic surface-mount crystal oscillator from the DS4-XO series, manufactured by Analog Devices Inc./Maxim Integrated. It generates a nominal output frequency of 622.08MHz using a fundamental AT-cut crystal and PLL technology. The device features LVPECL differential outputs with an active-high logic enable pin. It operates on a 3.3V ±5% supply voltage (3.135V to 3.465V) within a temperature range of -40°C to +85°C. Key electrical characteristics include a typical phase jitter of less than 0.7ps RMS (12kHz to 20MHz), a frequency stability of ±50ppm over the full operating range, and an operating current of up to 100mA under load.

Programmable Timers And Oscillators Feature Summary

• Low Phase Jitter: Typical integrated phase jitter is < 0.7ps RMS from 12kHz to 20MHz.
• LVPECL Output Driver: Provides differential LVPECL outputs with defined high/low voltages relative to VCC - 2.0V bias.
• Compact Package: Housed in a 5.0mm x 3.2mm x 1.49mm, 10-pin LCCC ceramic package with an exposed paddle.
• Frequency Stability: Maintains ±50ppm total frequency stability over temperature, aging, load, and supply variations.

Programmable Timers And Oscillators Applications

• InfiniBand
• BPON/GPON
• Ethernet
• 10GbE
• SONET/SDH

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 for End-of-Life (EOL) notices or Product Change Notifications (PCN) prior to procurement, as availability may be restricted.

Programmable Timers And Oscillators Selection Notes

Select the DS4622P+ variant specifically for LVPECL output requirements; the 'D' suffix denotes LVDS. Ensure the design supports the required 3.3V power rail and thermal dissipation for the LCCC package. Verify that the PCB layout accommodates the 10-pin LCCC footprint and leaves the exposed paddle unconnected.

Programmable Timers And Oscillators Part Context

The DS4622P+ belongs to the Maxim DS4-XO series of ceramic surface-mount crystal oscillators. This family includes various frequencies such as 125MHz, 155.52MHz, and 312.5MHz. The 'P+' suffix indicates the specific LVPECL output configuration and lead-free/RoHS-compliant packaging with gold over nickel lead finish.
