552ARI-01LFT集成電路（IC）的時鐘發(fā)生器PLL頻率合成器規(guī)格書PDF中文資料

Description

The ICS552A-01 produces 8 low-skew copies of the

multiple input clock or fundamental, parallel-mode

crystal. Unlike other clock drivers, these parts do not

require a separate oscillator for the input. Using IDT’s

patented Phase-Locked Loop (PLL) to multiply the input

frequency, it is ideal for generating and distributing

multiple high-frequency clocks. This is a single chip

used for 3 different applications:

1) ICS552A-01 (A mode) — an Oscillator mutiplier

2) ICS552A-01 (B mode) — a Dual 1:4 buffer

3) ICS552A-01 (C mode) — a 1:8 Oscillator buffer
