2:1, single-ended multiplexer ICS83052I data sheet ICS83052I revision b december 8, 2011 1 ? 2011 integrated device technology, inc. g eneral d escription the ICS83052I is a low skew, 2:1, single-ended multiplexer. the ICS83052I has two selectable single-ended clock inputs and one single-ended clock output. the output has a v ddo pin which may be set at 3.3v, 2.5v, or 1.8v, making the device ideal for use in voltage trans-lation 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 an 8 tssop. b lock d iagram p in a ssignment f eatures ? 2:1 single-ended multiplexer ? q nominal output impedance: 15 (v ddo = 3.3v) ? maximum output frequency: 250mhz ? propagation delay: 2.7ns (maximum), (v dd = v ddo = 3.3v) ? input skew: 160ps (maximum), (v dd = v ddo = 3.3v) ? part-to-part skew: 490ps (maximum), (v dd = v ddo = 3.3v) ? additive phase jitter, rms at 155.52mhz (12khz - 20mhz): 0.18ps (typical), (v dd = v ddo = 3.3v) ? operating supply modes: v dd /v 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 standard (rohs 5) and lead-free (rohs 6) packages clk0 clk1 sel0 oe q ICS83052I 8-lead tssop 4.40mm x 3.0mm x 0.925mm package body g package top view v ddo gnd clk1 v dd 1 2 3 4 q sel0 clk0 oe 8 7 6 5
