Beware of Chinese sellers, especially those who claim "USA Seller" or "Ships from USA". They send Chinese junk to agents in USA for re-shipment to you. Check seller country by clicking on the feedback number and checking the line "Member since..."
The CDCE706 is one of the smallest and powerful PLL synthesizer / multiplier / divider available today. Despite its small physical outlines, the CDCE706 is very flexible. It has the capability to produce an almost independent output frequency from a given input frequency.
The input frequency can be derived from a LVCMOS, differential input clock, or a single crystal. The appropriate input waveform can be selected via the SMBus data interface controller.
To achieve an independent output frequency the reference divider M and the feedback divider N for each PLL can be set to values from 1 up to 511 for the M-Divider and from 1 up to 4095 for the N-Divider. The PLL-VCO (voltage controlled oscillator) frequency than is routed to the free programmable output switching matrix to any of the six outputs. The switching matrix includes an additional 7-bit post-divider (1-to-127) and an inverting logic for each output.
The deep M/N divider ratio allows the generation of zero ppm clocks from any reference input frequency (e.g., a 27-MHz).
The CDCE706 includes three PLLs of those one supports SSC (spread-spectrum clocking). PLL1, PLL2, and PLL3 are designed for frequencies up to 300 MHz and optimized for zero-ppm applications with wide divider factors.
PLL2 also supports center-spread and down-spread spectrum clocking (SSC). This is a common technique to reduce electro-magnetic interference. Also, the slew-rate controllable (SRC) output edges minimize EMI noise.
Based on the PLL frequency and the divider settings, the internal loop filter components will be automatically adjusted to achieve high stability and optimized jitter transfer characteristic of the PLL.
The device supports non-volatile EEPROM programming for easy-customized application. It is preprogrammed with a factory default configuration (see Figure 13) and can be reprogrammed to a different application configuration before it goes onto the PCB or re-programmed by in-system programming. A different device setting is programmed via the serial SMBus Interface.
Two free programmable inputs, S0 and S1, can be used to control for each application the most demanding logic control settings (outputs disable to low, outputs 3-state, power down, PLL bypass, etc).

Purchases can only be changed or cancelled before payment.
Transit time 5-7 bus days in USA, however USPS does not guarantee these times, and can exceed them. If you have any time constraints, contact seller before bidding / buying, so we can both come to an agreement.
No cancellation possible after Payment. PAYMENT CLOSES ORDER AND COMMITS IT FOR SHIPPING. Your shipping label is created and billed along with insurance the moment you click "PAY". Paypal and insurance charges are non-recoverable. Any returns not resulting from seller wrongdoing will be assessed a restocking fee of 18% and will forfeit shipping costs.
International transit times can reach 8 weeks, 10 weeks for Italy and Brazil. You need to contact seller for alternate shipping options at extra cost if this is not acceptable to you.
