Jitter Attenuator & Multiplier ICS813252I-02 OBSOLETE DATA SHEET The ICS813252I-02 is a PLL based synchronous multiplier that is optimized for PDH or SONET to Ethernet clock jitter attenuation and frequency translation. The device contains two internal frequency multiplication stages that are cascaded in series.The stage is a VCXO PLL that is optimized to provide reference clock jitter attenuation. The second stage is a frequency multiplier that provides the low jitter, high frequency Ethernet output clock that easily meets Gigabit and 10 Gigabit Ethernet jitter requirements. Pre-divider and output divider multiplication ratios are selected using device selection control pins. The multiplication ratios are optimized to support most common clock rates used in PDH, SONET and Ethernet applications. The VCXO requires the use of an external, inexpensive pullable crystal. The VCXO uses external passive loop components which allows of the PLL loop bandwidth and damping characteristics. The device is packaged in a space-saving 32-VFQFN package and supports industrial temperature range. PIN ASSIGNMENT • Two LVPECL outputs Each output supports independent frequency selection at 25MHz, 125MHz, 156.25MHz and 312.5MHz • Two differential inputs support the following input types LVPECL, LVDS, LVHSTL, SSTL, HCSL • Accepts input frequencies from 8kHz to 155.52MHz including 8kHz, 1.544MHz, 2.048MHz, 19.44MHz, 25MHz, 77.76MHz, 125MHz and 155.52MHz • Attenuates the phase jitter of the input clock by using a lowcost pullable fundamental mode VCXO crystal • VCXO PLL bandwidth can be optimized for jitter attenuation and reference tracking using external loop connection • FemtoClock frequency multiplier provides low jitter, high frequency output • Absolute pull range 50ppm • FemtoClock VCO frequency 625MHz • RMS phase jitter 125MHz, using a 25MHz crystal 10kHz 20MHz 1.3ps maximum • 3.3V supply voltage • -40°C to 85°C ambient operating temperature • Available in lead-free RoHS 6 package • For functional replacement device use 813N252CKI-02LF nCLK1 CLK1 VCC nCLK0 CLK0 XTAL_OUT XTAL_IN VCCX LF1 LF0 ISET VEE CLK_SEL VCC RESERVED VEE 32 31 30 29 28 27 26 25 5 ICS813252I-02 20 9 10 11 12 13 14 15 16 VEE nQB QB VCCO nQA QA VEE ODASEL_0 PDSEL_2 PDSEL_1 PDSEL_0 VCC VCCA ODBSEL_1 ODBSEL_0 ODASEL_1 32-Lead VFQFN 5mm x 5mm x package body K Package Top View 2016 Integrated Device Technology, Inc.
