## Summary of the PhaseLink PLL701 Low EMI Spread Spectrum Multiplier Clock Datasheet:

This document is a datasheet for the PhaseLink PLL701, a low EMI spread spectrum multiplier clock. Here's a breakdown of the key information:

Core Function: The PLL701 takes an input clock frequency (30-120 MHz) and multiplies it (1x, 2x, or 4x) while applying spread spectrum modulation to reduce electromagnetic interference (EMI).

Key Features & Specs:

️· Input Frequency: 30 MHz - 120 MHz
️· Supply Voltage: 3.15V - 3.45V
️· Output Characteristics: VOH > 2.4V, VOL < 0.4V (with specified load)
️· Control Inputs: S0, S1, S2, S3 - Used to select the multiplication factor and spread spectrum settings via internal pull-up/down resistors.
️· Timing: Rise/Fall times are typically around 0.85 - 0.95ns. Cycle-to-cycle jitter is specified as < 100ps.
️· Package: SOIC
️· Absolute Maximum Ratings: Includes supply voltage limits, input/output voltage ranges, soldering temperature, storage temperature, and operating temperature (-40°C to +85°C).
️· Electrical Specifications: Details DC and AC characteristics like input/output currents, voltage levels, input capacitance, and dynamic supply current.

Key Applications: The PLL701 is designed to reduce EMI in clock-sensitive applications where minimizing interference is crucial.

Important Notes:

️· The datasheet emphasizes that operating the device outside the absolute maximum ratings may cause permanent damage.
️· PhaseLink reserves the right to change specifications without notice.
️· The product is not authorized for use in life-support applications without express written approval.



In essence, this datasheet provides all the necessary technical information for engineers and designers to properly implement and utilize the PhaseLink PLL701 in their electronic designs.
