Micrel, Inc. 3.3V, PRECISION, 33MHz to 500MHz PROGRAMMABLE LVPECL AND HSTL BUS CLOCK SYNTHESIZER Precision Edge® Precision ESdYg89e5®36L SY89536L FEATURES s Integrated synthesizer plus fanout buffers, clock dividers, and translator in a single 64-pin package s Accepts any reference input between 14MHz to 160MHz (single-ended or differential) s 33MHz to 500MHz output frequency range s LVPECL and HSTL outputs s 3.3V ±10% power supply s Low jitter: <50ps cycle-to-cycle s Low pin-to-pin skew: <50ps s TTL/CMOS compatible control logic s 3 independently programmable output frequency banks: 9 differential output pairs @BankB (HSTL) 2 differential output pairs @BankA (LVPECL) 2 differential output pairs @BankC (LVPECL) s Available in 64-pin EPAD-TQFP DESCRIPTION Precision Edge® The SY89536L programmable clock synthesizer is part of a 3.3V, high-frequency, precision PLL-based clock synthesizer family optimized for multi-frequency, large clocktree applications. This device integrates the following blocks into a single monolithic IC: PLL (Phase-Lock-Loop)-based synthesizer Fanout buffer Clock generator (divider) Logic translation (LVPECL, HSTL) The SY89536L includes a flexible input design that accepts any reference input; single-ended LVTTL/CMOS, SSTL and differential LVPECL, LVDS, HSTL, and CML. 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...
