Si5317 PIN-CONTROLLED 1711 MHZ JITTER CLEANING CLOCK Features Provides jitter attenuation for any clock Selectable output clock signal frequency format: LVPECL, LVDS, CML or CMOS One clock input / two clock outputs Single supply: 1.8, 2.5, or 3.3 V Input/output frequency range: 1711 MHz Loss of lock and loss of signal alarms Ultra low jitter: 300 fs (12 kHz20 MHz) typical VCO freeze during LOS/LOL Simple pin control interface On-chip voltage regulator with high PSRR Selectable loop bandwidth for jitter attenuation: 60 Hz8.4 kHz Small size: 6 x 6 mm, 36-QFN Meets OC-192 GR-253-CORE jitter Wide temperature range: 40 to specifications +85 C Ordering Information: Applications See page 40. Data converter clocking Switches and routers Wireless infrastructure Medical instrumentation Networking, SONET/SDH Test and measurement Pin Assignments Description The Si5317 is a flexible 1:1 jitter cleaning clock for high-performance applications 36 35 34 33 32 31 30 29 28 that require jitter attenuation without clock multiplication. The Si5317 accepts a RST 1 27 FRQSEL3 single clock input ranging from 1 to 711 MHz and generates two low jitter clock FRQTBL 2 26 FRQSEL2 outputs at the same frequency. The clock frequency range and loop bandwidth are 3 25 FRQSEL1 LOS selectable from a simple look-up table. The Si5317 is based on Skyworks NC 4 24 FRQSEL0 GND Solutions 3rd-generation DSPLL technology, which provides jitter attenuation on VDD 5 23 BWSEL1 Pad any frequency in a highly integrated PLL solution that eliminates the need for XA 6 22 BWSEL0 external VCXO and loop filter components. The DSPLL loop bandwidth is user XB 7 21 NC GND 8 20 INC selectable, providing jitter performance optimization at the application level.
