DUAL 2:1 AND 1:2, DIFFERENTIAL-TO-LVPECL/ECL MULTIPLEXER ICS85354 The ICS85354 is a dual 2:1 and 1:2 Multiplexer and a member of the HiPerClockSTM family of high HiPerClockS performance clock solutions from IDT. The 2:1 Multiplexer allows one of 2 inputs to be selected onto one output pin and the 1:2 MUX switches one input to one of two outputs. This device is useful for multiplexing multi-rate Ethernet PHYs which have 100 M bit and 1000 bit transmit/receive pairs onto an optical SFP module which has a single transmit/receive pair. See Application Section for further information. The ICS85354 is optimized for applications requiring very high performance and has a maximum operating frequency of 3GHz. The device is packaged in a small, 3mm x 3mm VFQFN package, making it ideal for use on space-constrained boards. • Three LVPECL outputs • Three differential clock inputs • CLKx/CLKx pairs can accept the following differential input levels LVPECL, LVDS, CML • Maximum output frequency 3.2GHz • Part-to-part skew 200ps maximum • Propagation delay QA/QA 450ps maximum QBx/QBx 430ps maximum • LVPECL mode operating voltage supply range: VCC = 2.375V to 3.465V, VEE = 0V • ECL mode operating voltage supply range: VCC = 0V, VEE = -3.465V to -2.375V-40°C to 85°C ambient operating temperature • Available in both standard RoHS 5 and lead-free RoHS 6 packages Block Diagram CLK_SELA Pulldown CLKA0 Pulldown CLKA0 Pullup/Pulldown CLKA1 Pulldown CLKA1 Pullup/Pulldown CLKB Pulldown CLKB Pullup/Pulldown CLK_SELB Pulldown Pin Assignment QA CLK_SELA VCC 16 15 14 13 QB0 1 12 CLKA0 QB0 2 11 CLKA0 QB1 3 10 CLKA1 QB1 4 9 CLKA1 5 6 78 CLKB CLK_SELB Ordering Information Table Ordering Information Part/Order Number 85354AK 85354AKT 85354AKLF 85354AKLFT Marking 354A 54AL Package 16 Lead VFQFN 16 Lead VFQFN “Lead-Free” 16 Lead VFQFN “Lead-Free” 16 Lead VFQFN Shipping Packaging Tube 2500 Tape & Reel Tube 2500 Tape & Reel Temperature -40°C to 85°C -40°C to 85°C -40°C to 85°C -40°C to 85°C NOTE Parts that are ordered with an "LF" suffix to the part number are the Pb-Free configuration and are RoHS compliant.
