DESCRIPTION

· The Si5315 is a jitter-attenuating clock multiplier designed for Gb and 10G Synchronous Ethernet, SONET/SDH, and PDH (T1/E1) applications.

· It supports SyncE EEC options 1 and 2 when used with a compatible timing card.

· The device accepts dual clock inputs from 8 kHz to 644.53 MHz and generates two equal frequency-multiplied clock outputs within the same range.

· Based on Skyworks Solutions' third-generation DSPLL® technology, it eliminates the need for external VCXO and loop filter components.

FEATURES

· Provides jitter attenuation and frequency translation between SONET/PDH and Ethernet.

· Supports ITU-T G.8262 Synchronous Ethernet equipment slave clock requirements.

· Two clock inputs and two clock outputs with a frequency range of 8 kHz–644 MHz.

· Ultra-low jitter: 0.23 ps RMS (1.875–20 MHz) and 0.47 ps RMS (12 kHz–20 MHz).

· Selectable loop bandwidth for jitter attenuation: 60 to 8.4 kHz.

· Programmable output clock signal format: LVPECL, LVDS, CML, or CMOS.

· Single supply: 1.8, 2.5, or 3.3 V with on-chip voltage regulator and high PSRR.

· Small size: 6 x 6 mm, 36-QFN, and wide temperature range: –40 to +85 ºC.

APPLICATIONS

· Synchronous Ethernet line cards.

· SONET OC-3/12/48 line cards.

· PON OLT/ONU and Carrier Ethernet switches/routers.

· MSAN / DSLAM and T1/E1/DS3/E3 line cards.
