The SY898535XL is a 3.3V, low skew, 1:4 Crystal Oscillator/LVCMOS/LV
TTL-to-LVPECL fanout buffer with selectable single ended clock or crystal inputs. The clock input accepts LVCMOS or LVTTL input levels and translate them to 3.3V LVPECL levels. To eliminate runt pulses on the outputs during asynchronous assertion/de-asserti
on of the clock enable pin, the clock enable is synchronized with the input signal.The SY898535XL operates from a 3.3V ±5% supply and is guaranteed over the full industrial temperature range of –40°C to +85°C. The SY898535XL is part of Micrel’s high-speed, Precision Edge® product line.
Additional Features
Provides four differential 3.3V LVPECL copies
Selects between single-ended CLK or crystal inputs
CLK accepts LVCMOS or LVTTL input levels
Guaranteed AC performance over temperature and supply voltage:
235MHz Maximum output frequency
<1.65ns Propagation delay (In-to-Q)
<30ps Output skew
<200ps Part-to-part skew
Additive phase jitter, RMS: 0.09ps (typical)
3.3V ±5% supply voltage
–40°C to +85°C industrial temperature operating range
Available in a 20-pin TSSOP package
