SCAS815I – OCTOBER 2005 – REVISED NOVEMBER 2008 PROGRAMMABLE 3-PLL CLOCK SYNTHESIZER/MULTIPLIER/DIVIDER • High-Performance 3:6 PLL-Based Clock Synthesizer/Multiplier/Divider • User-Programmable PLL Frequencies • EEPROM Programming Without the Need to Apply High Programming Voltage • Easy In-Circuit Programming via SMBus Data Interface • Wide PLL Divider Ratio Allows 0-ppm Output Clock Error • Clock Inputs Accept a Crystal, a Single-Ended LVCMOS, or a Differential Input Signal • Accepts Crystal Frequencies From 8 MHz to 54 MHz • Accepts LVCMOS or Differential Input Frequencies up to 200 MHz • Two Programmable Control Inputs [S0/S1, The CDCE706 is one of the smallest and most A0/A1] for User-Defined Control Signals powerful PLL synthesizer/multiplier/dividers available • Six LVCMOS Outputs With Output Frequencies today. Despite its small physical outline, the up to 300 MHz CDCE706 is very flexible. It has the capability to produce an almost independent output frequency • LVCMOS Outputs Can Be Programmed for from a given input frequency. Complementary Signals • Free Selectable Output Frequency via The input frequency can be derived from an Programmable Output Switching Matrix [6×6] LVCMOS, differential input clock, or single crystal. The appropriate input waveform can be selected via Including 7-Bit Post-Divider for Each Output the SMBus data interface controller. • PLL Loop Filter Components Integrated To achieve an independent output frequency, the • Low Period Jitter (Typically 60 ps) reference divider M and the feedback divider N for • Features Spread-Spectrum Clocking (SSC) for each PLL can be set to values from 1 to 511 for the Lowering System EMI M-divider and from 1 to 4095 for the N-divider. The • Programmable Output Slew-Rate Control PLL-VCO (voltage controlled oscillator) frequency (SRC) for Lowering System EMI then is routed from the programmable output switching matrix to any of the six outputs. The • 3.3-V Device Power Supply switching matrix includes an additional 7-bit • Industrial Temperature Range –40°C to 85°C post-divider (1 to 127) and an inverting logic for each • Development and Programming Kit for Easy output. PLL Design and Programming (TI ClockPro The deep M/N divider ratio allows the generation of Software) zero-ppm clocks from any reference input frequency • Packaged in 20-Pin TSSOP (e.g., 27 MHz). The CDCE706 includes three PLLs; of those, one supports spread-spectrum clocking (SSC). PLL1, PLL2, and PLL3 are designed for frequencies up to 300 MHz and optimized for zero-ppm applications with wide divider factors. 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
