PO74HSTL85331A
3.3V 1:4 Crystal Oscillator/
Differential Clock or Data Fanout Buffer
700MHz HSTL Potato Chip

FEATURES:
DESCRIPTION:
. Patented Technology
The PO74HSTL85331A is a low skew, high performance
. Four HSTL differential outputs
1-to-4 Crystal Oscillator/Differential-to-3.3V HSTL
. Selectable differential CLK, nCLK or crystal inputs fanout buffer of High Performance Clock Solutions from
. CLK, nCLK pair can accept the following differential PotatoSemi. The PO74HSTL85331A has selectable
input levels: LVPECL, LVDS, LVHSTL, SSTL, HCSL differential clock or crystal inputs. The CLK, nCLK pair
. Operating frequency up to 700MHz with 2pf load
can accept most standard differential input levels. The
. Operating frequency up to 550MHz with 5pf load
clock enable is internally synchronized to eliminate runt
. Operating frequency up to 400MHz with 15pf load pulses on the outputs during asynchronous
. Very low output pin to pin skew < 50ps
assertion/deassertion of the clock enable pin.
. 3.3-ns propagation delay (typical)
. 2.4V to 3.6V power supply
. Industrial temperature range: –40°C to 85°C
. 20-pin TSSOP package
Guaranteed output and part-to-part skew characteristics
make the PO74HSTL85331A ideal for those applications
demanding well defined performance and repeatability.

Notes:
1. For conditions shown as Max. or Min., use appropriate value specified under Electrical Characteristics for the applicable device type.
2. Typical values are at Vcc = 3.3V, 25°C ambient.
3. This parameter is guaranteed but not tested.
4. Not more than one output should be shorted at one time. Duration of the test should not exceed one second.
