CY26049-22 FailSafe PacketClock Global Communications Clock Generator • Fully integrated phase-locked loop PLL • output • PLL driven by a crystal oscillator that is phase aligned with external reference • 100-MHz output from 10-MHz input • Low-jitter, high-accuracy outputs • 3.3V ± 5% operation • 16-lead TSSOP • Integrated high-performance PLL tailored for telecommunications frequency synthesis eliminates the need for external loop filter components • When reference is off, DCXO maintains clock outputs and SAFE pin indicates FailSafe conditions • DCXO maintains continuous operation should the input reference clock fail • Glitch-free transition simplifies system design • Works with commonly available, low-cost 10-MHz crystal • Zero-ppm error for all output frequencies • Compatible across industry standard design platforms • Industry standard package with x mm2 footprint and a height profile of just mm Logic Block Diagram input reference 10M Hz IC L K external pullable crystal 10M Hz XOUT F A ILS A F ETM CONTROL D IG IT A L CONTROLLED CRYSTAL O SCILLATOR PHASE LOCKED LOOP OUTPUT D IV ID E R CLKA 100M H z SAFE ICLK detected Cypress Semiconductor Corporation • 3901 North First Street • San Jose, CA 95134 • 408-943-2600 Pin Configuration CY26049-22 16-pin TSSOP Top View ICLK 1 NC 2 NC 3 NC 4 VDD 5 VSS 6 NC 7 XIN 8 16 NC 15 CLKA 14 NC 13 NC 12 VDD 11 VSS 10 SAFE 9 XOUT Pin Description Pin Number Pin Name Pin Description ICLK Reference Input Clock 10 MHz.
