Integrated Circuit Systems, Inc. ICS85454-01 DUAL 2:1/1:2 DIFFERENTIAL-TO-LVDS MULTIPLEXER The ICS85454-01 is a 2:1/1:2 Multiplexer and a member of the HiPerClockSTM family of high HiPerClockS performance clock solutions from ICS. The 2:1 Multiplexer allows one of 2 inputs to be select- ed onto one output pin and the 1:2 MUX switches one input to both of two outputs. This device may be useful for multiplexing multi-rate Ethernet PHYs which have 100Mbit and 1000Mbit transmit/receive pairs onto an optical SFP module which has a single transmit/receive pair. Another mode allows loop back testing and allows the output of a PHY transmit pair to be routed to the PHY input pair. For examples, please refer to the Application Information section of the data sheet. The ICS85454-01 is optimized for applications requiring very high performance and has a maximum operating frequency in 2.5GHz. The device is packaged in a small, 3mm x 3mm VFQFN package, making it ideal for use on space-constrained boards. • Dual 2:1/1:2 MUX • Three LVDS outputs • Three differential inputs • Differential inputs can accept the following differential levels LVPECL, LVDS, CML • Loopback test mode available • Maximum output frequency 2.5GHz • Part-to-part skew 250ps maximum • Additive phase jitter, RMS 0.05ps typical • Propagation delay 550ps maximum • 2.5V operating supply • -40°C to 85°C ambient operating temperature • Available in both standard and lead-free RoHS compliant packages BLOCK DIAGRAM SELB INB nINB QB nQB PIN ASSIGNMENT QB nQB SELA VDD INA0 nINA0 LOOP0 QA0 nQA0 16 15 14 13 QA0 1 12 INA0 nQA0 2 11 nINA0 QA1 3 10 INA1 nQA1 4 9 nINA1 5678 INB nINB SELB GND INA1 nINA1 TABLE ORDERING INFORMATION Part/Order Number 85454AK-01 Marking 5A01 Package 16 Lead VFQFN Shipping Packaging Tube Temperature -40°C to 85°C 85454AK-01T 5A01 16 Lead VFQFN 2500 Tape & Reel -40°C to 85°C 85454AK-01LF A01L 16 Lead "Lead-Free" VFQFN Tube -40°C to 85°C 85454AK-01LFT A01L 16 Lead "Lead-Free" VFQFN 2500 Tape & Reel -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.

ICS85454-01

DUAL 2:1/1:2 DIFFERENTIAL-TO-LVDS MULTIPLEXER

The ICS85454-01 is a 2:1/1:2 Multiplexer and
a member of the HiPerClockSTM family of high

HiPerClockS performance clock solutions from ICS. The 2:1

Multiplexer allows one of 2 inputs to be select-
ed onto one output pin and the 1:2 MUX
switches one input to both of two outputs. This device
may be useful for multiplexing multi-rate Ethernet PHYs
which have 100Mbit and 1000Mbit transmit/receive
pairs onto an optical SFP module which has a single
transmit/receive pair. Another mode allows loop back
testing and allows the output of a PHY transmit pair to be
routed to the PHY input pair. For examples, please refer to
the Application Information section of the data sheet.

The ICS85454-01 is optimized for applications requiring very high performance and has a maximum operating frequency in 2.5GHz. The device is packaged in a small, 3mm x 3mm VFQFN package, making it ideal for use on space-constrained boards.
• Dual 2:1/1:2 MUX
• Three LVDS outputs
• Three differential inputs
• Differential inputs can accept the following differential
levels LVPECL, LVDS, CML
• Loopback test mode available
• Maximum output frequency 2.5GHz
• Part-to-part skew 250ps maximum
• Additive phase jitter, RMS 0.05ps typical
• Propagation delay 550ps maximum
• 2.5V operating supply
• -40°C to 85°C ambient operating temperature
• Available in both standard and lead-free RoHS compliant
packages
