ICS854058 8:1 DIFFERENTIAL-TO-LVDS CLOCK MULTIPLEXER PRELIMINARY GENERAL DESCRIPTION The ICS854058 is an 8:1 Differential-to-LVDS Clock Multiplexer which can operate up to 2.5GHz and is a member of the HiPerClockS™ family of High Performance Clock Solutions from ICS. The ICS854058 has 8 selectable differential clock in- puts.The PCLK, nPCLK input pairs can accept LVPECL, LVDS, CML or SSTL levels. The fully differential architecture and low propagation delay make it ideal for use in clock distribution cir- cuits.The select pins have internal pulldown resistors.The SEL2 pin is the most significant bit and the binary number applied to the select pins will select the same numbered data input (i.e., 000 selects PCLK0, nPCLK0). FEATURES • High speed 8:1 differential multiplexer • 1 differential LVDS output • 8 selectable differential PCLK, nPCLK inputs • PCLKx, nPCLKx pairs can accept the following differential input levels: LVPECL, LVDS, CML, SSTL • Maximum output frequency: 2.5GHz • Translates any single ended input signal to LVDS levels with resistor bias on nPCLKx input • Part-to-part skew: TBD • Propagation delay: 595ps (typical) • Supply voltage range: 3.135V to 3.465V • -40°C to 85°C ambient operating temperature BLOCK DIAGRAM PIN ASSIGNMENT HiPerClockS™ ICS ICS854058 24-Lead, 173-MIL TSSOP 4.4mm x 7.8mm x 0.92mm body package G Package Top View PCLK0 nPCLK0 PCLK1 nPCLK1 VDD SEL0 SEL1 SEL2 PCLK2 nPCLK2 PCLK3 nPCLK3 PCLK7 nPCLK7 PLCK6 nPCLK6 VDD Q0 nQ0 GND PCLK5 nPCLK5 PCLK4 nPCLK4 PCLK0 nPCLK0 PCLK1 nPCLK1 PCLK2 nPCLK2 PCLK3 nPCLK3 000 011 001 010 SEL1 SEL0 Q0 nQ0 PCLK4 nPCLK4 PCLK5 nPCLK5 PCLK6 nPCLK6 PCLK7 nPCLK7 SEL2 100 111 101 110 1 2 3 4 5 6 7 8 9 10 11 12 24 23 22 21 20 19 18 17 16 15 14 13 The Preliminary Information presented herein represents a product in prototyping or pre-production.
