ICS8432-111 700MHZ/350MHZ DIFFERENTIAL-TO-3.3V LVPECL FREQUENCY SYNTHESIZER PRODUCT DISCONTINUATION NOTICE - LAST TIME BUY EXPIRES JULY 31, 2015 The ICS8432-111 is a general purpose, dual output Differential-to-3.3V LVPECL High Frequency Synthesizer. The ICS8432-111 has a selectable differential CLK, nCLK pair or LVCMOS/LVTTL TEST_CLK. The TEST_CLK input accepts LVCMOS or LVTTL input levels and translates them to 3.3V LVPECL levels. The CLK, nCLK pair can accept most standard differential input levels.The VCO operates at a frequency range of 200MHz to 700MHz. The VCO frequency is programmed in steps equal to the value of the input differential or single ended reference frequency. Output frequencies up to 700MHz for FOUT and 350MHz for FOUT/2 can be programmed using the serial or parallel interfaces to the logic. The low phase noise characteristics and the multiple frequency outputs of the ICS8432-111 makes it an ideal clock source for Fibre Channel 1 and 2, and applications. • Dual differential 3.3V LVPECL outputs • Selectable differential CLK, nCLK pair or LVCMOS TEST_ CLK • CLK, nCLK pair can accept the following differential input levels LVPECL, LVDS, LVHSTL, SSTL, HCSL • TEST_CLK can accept the following input types LVCMOS or LVTTL • Maximum FOUT frequency 700MHz Maximum FOUT/2 frequency 350MHz • CLK, nCLK or TEST_CLK input frequency 40MHz • VCO range 250MHz to 700MHz • Parallel or serial interface for programming counter and VCO frequency multiplier and dividers • RMS period jitter 5ps maximum • Cycle-to-cycle jitter 40ps maximum • 3.3V supply voltage • 0°C to 70°C ambient operating temperature • Available in lead-free RoHS 6 package • For functional replacement device use 8432DY-101LF BLOCK DIAGRAM PIN ASSIGNMENT nCLK nP_LOAD VCO_SEL M0 M1 M2 M3 VCO_SEL CLK_SEL TEST_CLK nCCLLKK S_LOAD S_DATA S_CLOCK nP_LOAD M0:M8 N0:N1 8432CY-111 PHASE DETECTOR 0 ÷2 ÷4 CONFIGURATION INTERFACE LOGIC FOUT nFOUT FOUT/2 nFOUT/2 32 31 30 29 28 27 26 25 24 CLK 23 TEST_CLK 22 CLK_SEL M8 4 N0 5 ICS8432-111 21 VCCA 20 S_LOAD 19 S_DATA 18 S_CLOCK VEE 8 17 MR TABLE ORDERING INFORMATION ICS8432-111 700MHZ/350MHZ DIFFERENTIAL-TO-3.3V LVPECL FREQUENCY SYNTHESIZER While the information presented herein has been checked for both accuracy and reliability, Integrated Device Technology, Inc.
