| Integrated Circuit Systems, Inc. ICS8733-01 700MHZ FORWARD ERROR CORRECTION DIFFERENTIAL-TO-3.3V LVPECL CLOCK GENERATOR The ICS8733-01 is a dual output, Differential- to-3.3V LVPECL Clock Generator and a HiPerClockS member of the HiPerClockS family of High Performance Clock Solutions from ICS. The ICS8733-01 is designed to be used for applica- tions utilizing Forward Error Correction FEC designs. The ICS8733-01 generates a 14/15 or a 15/14 output clock based upon the input reference clock in order to incorporate the FEC capability required by the application. Clock generation is performed by a fully integrated and low-jitter phase-locked loop. The ICS8733-01 accepts any differential signal as its input with an input reference frequency range of 36.27MHz to 750MHz. There are two LVPECL outputs which can generate output frequencies of 38.88MHz to 700MHz. • Clock synthesis of 14/15 or 15/14 of the input reference clock to be utilized in Forward Error Correction FEC applications • Fully integrated PLL • 2 differential 3.3V LVPECL outputs • 1 differential clock input pair • CLK, nCLK pair can accept the following differential input levels LVPECL, LVHSTL, LVDS, SSTL, HCSL • Output frequency range 38.88MHz - 700MHz • Input frequency range 36.27MHz - 750MHz • VCO range 200MHz to 700MHz • PLL bypass and test modes that support in-circuit testing and on-chip functional block characterization • Cycle-to-cycle jitter 20ps typical • Period jitter TBD • Output skew 10ps maximum • 3.3V supply voltage • 0°C to 70°C ambient operating temperature BLOCK DIAGRAM DIV_SEL0 DIV_SEL1 PLL_SEL CLK nCLK “N” ÷14 0 ÷15 1 FEC_NSEL ÷¼ ÷2 ÷4 10 11 PIN ASSIGNMENT nc PLL_SEL VCC nc nc FEC_NSEL FEC_MSEL VEE TEST_SEL TEST_EN VEE 32 31 30 29 28 27 26 25 4 ICS8733-01 21 9 10 11 12 13 14 15 16 CLK n_CLK VCCA DIV_SEL0 DIV_SEL1 nc MR FOUT1 nFOUT1 VEE nFOUT0 FOUT0 VCCO nFOUT1 FOUT1 VCC TEST 0 ÷15 0 1 ÷14 1 “M” TABLE ORDERING INFORMATION Part/Order Number ICS8733BY-01 ICS8733BY-01T Marking ICS8733BY-01 ICS8733BY-01 Package Count 32 Lead LQFP 250 per tray 32 Lead LQFP on Tape and Reel 1000 Temperature 0°C to 70°C 0°C to 70°C While the information presented herein has been checked for both accuracy and reliability, Integrated Circuit Systems, Incorporated ICS assumes no responsibility for either its use or for infringement of any patents or other rights of third parties, which would result from its use.
