SY89610L Datasheet | Micrel Semiconductor

.Data Sheet.co.kr 77.75MHz to 694MHz Jitter Attenuator and Low Phase Noise Frequency Synthesizer General Description The SY89610L is a 3.3V, fully differential jitter attenuator and frequency synthesizer that accepts a noise clock between 19.44MHz and 694MHz, depending on I/O frequency selection. The output provides an ultra-low jitter clock frequency between 77.75MHz and 694MHz covering SONET/SDH, Gigabit Ethernet, Fibre Channel, SAS, SATA, and many other munication standards. The output jitter of the SY89610L is typically 1ps RMS. It has a 1k Hz to 10k Hz programmable loop bandwidth to acmodate different jitter attenuation applications and PLL requirements. The auto-tune circuit enables precision frequency calibration. The differential input includes Micrel’s unique, 3-pin input termination architecture that interfaces to LVPECL, LVDS or CML differential signals, (AC- or DC-coupled) as small as 100m V without any level-shifting or termination resistor networks in the signal path. For ACcoupled input interface applications, an on-board output reference voltage (VREF-AC) is provided to bias the VT pin. The outputs are patible with 400m V typical swing into 50Ω loads, with rise/fall times guaranteed to be less than 250ps. The SY89610L operates at 3.3V ±10% supply and the output can acmodate 1.8V to 3.3V operation with the dedicated output supply. The part is guaranteed to operate over the full industrial temperature range (- 40°C to +85°C). The SY89610L is part of Micrel’s Precision Edge® product line.
