DATASHEET CLOCK SLICER USER CONFIGURABLE PECL INPUT ZERO DELAY BUFFER ICS527-02 The ICS527-02 Clock Slicer is the most flexible way to generate a CMOS output clock from a PECL input clock with zero skew. The user can easily configure the device to produce nearly any output clock that is multiplied or divided from the input clock. The part supports non-integer multiplications and divisions. A SYNC pulse indicates when the rising clock edges are aligned with zero skew. Using Phase-Locked Loop PLL techniques, the device accepts an input clock up to 200 MHz and produces an output clock up to 160 MHz. The ICS527-02 aligns rising edges on PECLIN with FBIN at a ratio determined by the reference and feedback dividers. For a PECL input and output clock with zero delay, use the ICS527-04. For a CMOS input and PECL output with zero delay, use the ICS527-03. • Packaged as 28-pin SSOP 150 mil body • Synchronizes fractional clocks rising edges • PECL IN to CMOS OUT • Pin selectable dividers • Zero input to output skew • User determines the output software needed • Slices frequency or period • Input clock frequency of MHz to 200 MHz • Output clock frequencies from 4 MHz to 160 MHz • Very low jitter • Duty cycle of 45/55 • Operating voltage of V • Advanced, low-power CMOS process • Industrial temperature version available NOTE EOL for non-green parts to occur on 5/13/10 per PDN U-09-01 Block Diagram PECLIN R6:R0 7 Reference Divider FBIN Feedback Divider 7 F6:F0 2 VDD Phase Comparator, Charge Pump, and Loop Filter VCO SYNC 2 GND PDTS Output Divider 2 S1:S0 33 ohm CLK1 Divide DIV2 33 ohm CLK2 Feedback can come from CLK1 or CLK2 not both IDT / ICS CLOCK SLICER USER CONFIGURABLE PECL INPUT ZERO DELAY BUFFER 1 ICS527-02 CLOCK SLICER USER CONFIGURABLE PECL INPUT ZERO DELAY BUFFER PECL ZDB AND MULTIPLIER/DIVIDER Pin Assignment D IV 2 P E C LIN P E C LIN O E C LK 2 CLK1 Ordering Information Part / Order Number 527R-02* 527R-02T* 527R-02I* 527R-02IT* 527R-02LF 527R-02LFT 527R-02ILF 527R-02ILFT Marking ICS527R-02 ICS527R-02 ICS527R-02I ICS527R-02I 527R02LF 527R02ILF Shipping Packaging Tubes Tape and Reel Tubes Tape and Reel Tubes Tape and Reel Tubes Tape and Reel Package 28-pin SSOP 28-pin SSOP 28-pin SSOP 28-pin SSOP 28-pin SSOP 28-pin SSOP 28-pin SSOP 28-pin SSOP Temperature 0 to +70° C 0 to +70° C -40 to +85° C -40 to +85° C 0 to +70° C 0 to +70° C -40 to +85° C -40 to +85° C *NOTE EOL for non-green parts to occur on 5/13/10 per PDN U-09-01 While the information presented herein has been checked for both accuracy and reliability, Integrated Device Technology IDT assumes no responsibility for either its use or for the infringement of any patents or other rights of third parties, which would result from its use.

DATASHEET

CLOCK SLICER USER CONFIGURABLE PECL INPUT ZERO DELAY BUFFER ICS527-02

The ICS527-02 Clock Slicer is the most flexible way to generate a CMOS output clock from a PECL input clock with zero skew. The user can easily configure the device to produce nearly any output clock that is multiplied or divided from the input clock. The part supports non-integer multiplications and divisions. A SYNC pulse indicates when the rising clock edges are aligned with zero skew. Using Phase-Locked Loop PLL techniques, the device accepts an input clock up to 200 MHz and produces an output clock up to 160 MHz.

The ICS527-02 aligns rising edges on PECLIN with FBIN at a ratio determined by the reference and feedback dividers.

For a PECL input and output clock with zero delay, use the ICS527-04.

For a CMOS input and PECL output with zero delay, use the ICS527-03.
• Packaged as 28-pin SSOP 150 mil body
• Synchronizes fractional clocks rising edges
