Device Overview

Summary

The SY89531L programmable clock synthesizer/driver is part of a 3.3V, high-frequency, precision PLL-based clock synthesizer family optimized for multi-frequency, multi-processor server, enterprise networking and other computing applications that require the highest precision and integration. The device integrates the following blocks into a single monolithic IC:
• PLL (Phase-Lock-Loop)-based synthesizer
• Fanout buffers
• Clock generator (dividers)
• Logic translation (LVPECL, HSTL)

This level of integration minimizes the additive jitter and part-to-part skew associated with the discrete alternative, resulting in superior system-level timing as well as reduced board space and power. For applications that must interface to a reference clock, see the SY89536L.

Additional Features
    • Low pin-to-pin skew: <50ps
    • 33MHz to 500MHz output frequency range
    • Direct interface to crystal: 14MHz to 18MHz
    • LVPECL/HSTL outputs
    • TTL/CMOS compatible control logic
    • 3 independently programmable output frequency banks:
      • 9 differential output pairs @BankB (HSTL)
      • 2 differential output pairs @BankA (LVPECL)
      • 2 differential output pairs @BankC (LVPECL)
    • ExtVCO input allows synthesizer and crystal interface to be bypassed
    • Available in 64-pin EPAD-TQFP
