ICS83054I Integrated Circuit Systems, Inc. 4:1, SINGLE-ENDED MULTIPLEXER GENERAL DESCRIPTION FEATURES The ICS83054I is a low skew, 4:1, Singleended Multiplexer and a member of the HiPerClockS™ HiPerClockS ™ family of High Performance Clock Solutions from ICS. The ICS83054I has four selectable single-ended clock inputs and one single-ended clock output. The output has a VDDO pin which may be set at 3.3V, 2.5V, or 1.8V, making the device ideal for use in voltage translation applications. An output enable pin places the output in a high impedance state which may be useful for testing or debug. The device operates up to 250MHz and is packaged in a 16 TSSOP. • 4:1 single-ended multiplexer ICS • Q nominal output impedance: 7Ω (VDDO =3 .3V) • Maximum output frequency: 250MHz • Propagation delay: 3ns (maximum), VDD = VDDO = 3.3V • Input skew: 225ps (maximum), VDD = VDDO = 3.3V • Part-to-part skew: 475ps (maximum), VDD = VDDO = 3.3V • Operating supply modes: VDD/VDDO 3.3V/3.3V 3.3V/2.5V 3.3V/1.8V 2.5V/2.5V 2.5V/1.8V • -40°C to 85°C ambient operating temperature • Available in both standard and lead-free RoHS-compliant packages BLOCK DIAGRAM PIN ASSIGNMENT Q nc OE CLK3 GND nc SEL1 CLK2 CLK0 CLK1 Q CLK2 1 2 3 4 5 6 7 8 16 15 14 13 12 11 10 9 VDDO nc CLK0 nc VDD nc CLK1 SEL0 CLK3 ICS83054I 16-Lead TSSOP 4.4mm x 5.0mm x 0.92mm package body G Package Top View SEL1 SEL0 OE 83054AGI www.icst.com/products/hiperclocks.html 1 REV.
