| Integrated Circuit Systems, Inc. ICS854057 4:1 OR 2:1 LVDS CLOCK MULTIPLEXER WITH INTERNAL INPUT TERMINATION The ICS854057 is a 4:1 or 2:1 LVDS Clock Mul- tiplexer which can operate up to 2GHz and is a HiPerClockS member of the HiPerClockS family of High Per- formance Clock Solutions from ICS. The PCLK, nPCLK pairs can accept most standard differen- tial input levels. Internal termination is provided on each dif- ferential input pair. The ICS854057 operates using a 2.5V sup- ply voltage. The fully differential architecture and low propa- gation delay make it ideal for use in high speed multiplexing applications. The select pins have internal pulldown resistors. Leaving one input unconnected pulled to logic low by the in- ternal resistor will transform the device into a 2:1 multiplexer. The SEL1 pin is the most significant bit and the binary num- ber applied to the select pins will select the same numbered data input i.e., 00 selects PCLK0, nPCLK0 . • High speed differential multiplexer.The device can be configured as either a 4:1 or 2:1 multiplexer • Single LVDS output • 4 selectable PCLK, nPCLK inputs with internal termination • PCLK, nPCLK pairs can accept the following differential input levels LVPECL, LVDS, CML, SSTL • Output frequency >2GHz • Part-to-part skew 200ps maximum • Propagation delay 800ps maximum • Additive phase jitter, RMS 66fs typical • 2.5V operating supply • -40°C to 85°C ambient operating temperature • Available in both, Standard and RoHS/Lead-Free compliant packages BLOCK DIAGRAM VT0 50 PCLK0 nPCLK0 50 PCLK1 nPCLK1 VT2 50 PCLK2 nPCLK2 50 PCLK3 nPCLK3 SEL1 Pulldown SEL0 Pulldown 854057AG PIN ASSIGNMENT VDD 1 PCLK0 2 VT0 3 nPCLK0 4 SEL1 5 SEL0 6 PCLK1 7 VT1 8 nPCLK1 9 GND 10 20 VDD 19 PCLK3 18 VT3 17 nPCLK3 16 Q 15 nQ 14 PCLK2 13 VT2 12 nPCLK2 11 GND ICS854057 20-Lead TSSOP 4.40mm x 6.50mm x 0.925mm body package G Package Top View TABLE ORDERING INFORMATION Part/Order Number Marking Package Shipping Packaging Temperature 854057AG ICS854057AG 20 lead TSSOP tube -40°C to 85°C 854057AGT ICS854057AG 20 lead TSSOP 2500 tape & reel -40°C to 85°C 854057AGLF ICS854057AGL 20 lead "Lead-Free" TSSOP tube -40°C to 85°C 854057AGLFT ICS854057AGL 20 lead "Lead-Free" TSSOP 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.
