M9999-010808 hbwhelp@micrel.com or (408) 955-1690 Input Output Device Crystal Reference BankA BankB BankC SY89532L X LVPECL LVPECL LVPECL SY89533L X LVPECL LVDS LVPECL SY89534L(1) X LVPECL LVPECL LVPECL SY89535L(1) X LVPECL LVDS LVPECL FEATURES Integrated synthesizer plus fanout buffers, clock drivers , and translator in a single 64-pin package 3.3V ±10% power supply Low jitter: <50ps cycle-to-cycle Low pin-to-pin skew: <50ps 33MHz to 500MHz output frequency range Direct interface to crystal: 14MHz to 18MHz LVPECL output (SY89532L), LVPECL/LVDS outputs (SY89533L) TTL/CMOS compatible control logic 3 independently programmable output frequency banks: • 9 differential output pairs @BankB (LVPECL/LVDS) • 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 The SY89532 and SY89533L programmable clock synthesizer/drivers are a 3.3V, high-frequency, precision PLL- based clock driver family optimized for multi-frequency, multi- processor server and synchronous computing applications that require the highest precision. These devices integrate the following blocks into a single monolithic IC: • PLL (Phase-Lock-Loop)-based synthesizer • Fanout buffers • Clock generator (dividers) • Logic translation (LVPECL, LVDS) 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 SY89534/5. 3.3V, PRECISION, 33MHz to 500MHz PROGRAMMABLE LVPECL AND LVDS BUS CLOCK SYNTHESIZER DESCRIPTION Precision Edge® SY89532L SY89533L APPLICATIONS Servers Workstations Parallel processor-based systems Other high-performance computing Communications Rev.: F Amendment: /0 Issue Date: January 2008 PRODUCT SELECTION GUIDE Note: 1.Refer to SY89534/35L data sheet for details.
