2:1 Single-Ended Multiplexer 8CA3052I Data Sheet GENERAL DESCRIPTION FEATURES The 8CA3052I is a low skew, 2:1, Single-ended Multiplexer. The 2:1 single-ended multiplexer 8CA3052I has two selectable single-ended clock inputs and one Q nominal output impedance: 15 (V = 3.3V) DDO single-ended clock output. The output has a V pin which may be DDO set at 3.3V, 2.5V, or 1.8V, making the device ideal for use in voltage Maximum output frequency: 250MHz translation applications. An output enable pin places the output in Propagation delay: 2.7ns (maximum), (V = V = 3.3V) DD DDO a high impedance state which may be useful for testing or debug. The device operates up to 250MHz and is packaged in an 8 TSSOP. Input skew: 160ps (maximum), (V = V = 3.3V) DD DDO Part-to-part skew: 490ps (maximum), (V = V = 3.3V) DD DDO Additive phase jitter, RMS at 155.52MHz (12kHz - 20MHz): 0.18ps (typical), (V = V = 3.3V) DD DDO Operating supply modes: V /V DD DDO 3.3V/3.3V 3.3V/2.5V 3.3V/1.8V 2.5V/2.5V 2.5V/1.8V -40C to 85C ambient operating temperature Available in lead-free (RoHS 6) package BLOCK DIAGRAM PIN ASSIGNMENT VDDO Q 1 8 Pulldown GND SEL0 2 7 CLK0 0 CLK1 CLK0 3 6 Q VDD 4 5 OE Pulldown CLK1 1 8CA3052I 8-Lead TSSOP 4.40mm x 3.0mm x 0.925mm package body Pulldown SEL0 PG8 Package Pullup OE Top View 2016 Integrated Device Technology, Inc 1 Revision A January 27, 20168CA3052I Data Sheet TABLE 1.
