Micrel, Inc. 3.3V, PRECISION, 33MHz to 500MHz PROGRAMMABLE LVPECL AND LVDS BUS CLOCK SYNTHESIZER PrecisPiroencSiYsEi8o9dn5g3Ee4d/®g35eL® SY89534L SY89535L 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 outputs (SY89534L) LVPECL and LVDS outputs (SY89535L) 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 (LVPECL/LVDS) 2 differential output pairs @BankA (LVPECL) 2 differential output pairs @BankC (LVPECL) s Available in 64-pin EPAD-TQFP Precision Edge® DESCRIPTION The SY89534L and SY89535L programmable clock synthesizers are a 3.3V, high-frequency, precision PLL-based family optimized for multi-frequency, large clock-tree applications that require the highest precision. These devices integrate the following blocks into a single monolithic IC: PLL (Phase-Lock-Loop)-based synthesizer Fanout buffer Clock generator (divider) Logic translation (LVPECL, LVDS) The SY89534L and SY89535L 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 ass...
