M2004-02-622.0800T

Clock Generators, PLLs, Frequency Synthesizers Overview

The M2004-02-622.0800T is a VCSO-based clock generator PLL designed for frequency translation and jitter attenuation in high-speed data communications systems. It features an integrated SAW delay line with a center frequency of 622.08 MHz, supporting input frequencies up to 175 MHz. The device provides low phase jitter (< 0.5 ps rms) and pin-selectable M and N dividers for flexible output scaling. It operates on a single 3.3V supply within a 9x9 mm ceramic leadless chip carrier package.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

• Integrated SAW delay line with 622.08 MHz VCSO center frequency
• Low phase jitter performance: < 0.5 ps rms (12kHz to 20MHz)
• Pin-selectable M divider (3-63) and N divider (1, 2, 4, 8)
• Supports differential LVDS/LVPECL and single-ended LVCMOS/LVTTL inputs

Clock Generators, PLLs, Frequency Synthesizers Applications

• OC-48/192 data clock generation
• Jitter attenuation in 2.5 or 10 Gb optical network line cards
• SONET/SDH compliant clock distribution

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific ordering suffix required for industrial temperature ranges (-40°C to +85°C), which typically involves an 'I' designation (e.g., M2004-02I622.0800). Confirm that the '-T' suffix corresponds to tape-and-reel packaging if applicable, as datasheet examples primarily list standard part numbers without explicit reel specifications.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this variant when a fixed 622.08 MHz internal VCO is required. Note that the M2004-02 lacks Hitless Switching with Phase Build-out (HS/PBO); choose the M2004-12 variant if SONET/SDH MTIE/TDEV compliance during reference clock reselection is necessary. Ensure external loop filter components are calculated based on the specific M-divider setting.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the M2004-x2 family of frequency translation PLLs from Integrated Circuit Systems (ICS). Variants include -02 (base), -12 (with HS/PBO), and others with fixed narrow bandwidth options. The M2004-02 serves as the foundational model for applications requiring basic jitter attenuation without hitless switching capabilities.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Cross-reference with other ICS M2004 variants or similar SAW-based PLLs only after verifying electrical compatibility and pinout alignment.
