ADN4670BSTZ集成電路（IC）的時鐘緩沖器驅動器規(guī)格書PDF中文資料

ADN4670BSTZ屬于集成電路（IC）的時鐘緩沖器驅動器。由亞德諾半導體技術有限公司制造生產的ADN4670BSTZ時鐘緩沖器，驅動器時鐘緩沖器和驅動器集成電路產品族中的產品用于幫助信號在系統(tǒng)中傳輸，常用作頻率/時間參考信號，以同步系統(tǒng)內的活動。盡管這些器件最常用到的功能就是緩沖（即，為使信號不受驅動負載的影響而從某個信號源復制信號），但是該產品族中的某些器件還能執(zhí)行其他功能，例如選擇性改變緩沖信號路徑、按某個整數(shù)值分割信號頻率，或進行所用電信號格式轉換。

GENERAL DESCRIPTION

The ADN4670 is a low voltage differential signaling (LVDS) clock driver that expands a differential clock input signal to 10 differential clock outputs. The device is programmable using a simple serial interface, so that one of two clock inputs can be selected (CLK0/CLK0 or CLK1/CLK1) and any of the differential outputs (Q0/Q0 to Q9/Q9) can be enabled or disabled (tristated). The ADN4670 is designed for use in 50 ? transmission line environments.

When the enable input EN is high, the device may be programmed by clocking 11 data bits into the shift register. The first 10 bits determine which outputs are enabled (0 = disabled, 1 = enabled), while the 11th bit selects the clock input (0 = CLK0, 1 = CLK1). A 12th clock pulse transfers data from the shift register to the control register.

The ADN4670 is fully specified over the industrial temperature range and is available in a 32-lead LFCSP and LQFP packages.
