Renesas MK1714-01R

时钟乘法器带旁路时钟，晶体CMOS

Overview

The MK1714-01 is a low cost, high performance clock synthesizer with selectable multipliers and percentages of spread spectrum designed to generate high frequency clocks with low EMI. Using analog/digital Phase Locked Loop (PLL) techniques, the device accepts an inexpensive, fundamental mode, parallel resonant crystal or clock input to produce a spread or dithered output. This reduces the EMI amplitude peaks at the odd harmonics by several dB. The OE pin places both outputs into a high impedance state for board level testing. The PD pin powers down the entire chip and the outputs are held low. See the MK1714-02 for other selections on input ranges and spreads.

Features • Packaged in 20 pin tiny SSOP • Operating voltage of 3.3V or 5V • Multiplier modes of x1, x2, x3, x4, x5, and x6 • Inexpensive 10 - 25 MHz crystal or clock input • OE pin tri-states the outputs for board testing • Power down pin stops the outputs low • Selectable frequency spread • Spread can be turned on or off • Advanced, low power CMOS process • Duty cycle of 40/60 • Industrial temperature range available • Available in Pb (lead) free package • Input frequency of 5 - 140 MHz (depending on mode) • Output frequency of 20 - 150 MHz (depending on mode)
