Status: In Production
The SY89610L is a 3.3V, fully differential frequency synthesizer jitter attenuating that accepts a noisy clock between 19.44MHz and 694MHz, depending on I/O frequency selection, and provides an ultra-low jitter clock signal. This corresponds to an output clock frequency between 77.75MHz and 694MHz covering SONET, SAS, SATA, Fibre Channel, and many other standards. Output jitter is typically 1psRMS. The SY89610L includes a 1kHz to 10kHz programmable loop bandwidth so it can accommodate different jitter attenuation applications and PLL requirements.
The differential input includes Micrel's unique, 3-pin input termination architecture that interfaces to LVPECL, LVDS or CML differential signals, (AC-coupled or DC-coupled) as small as 100mV without any level-shifting or termination resistor networks in the signal path. For AC-coupled input interface applications, an on-board output reference voltage (VREF-AC) is provided to bias the VT pin. The outputs are compatible with 400mV 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 accommodate 1.8V-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.
