MK2745-24STR集成电路（IC）的时钟发生器PLL频率合成器规格书PDF中文资料

描述 Description

The MK2745-24 is a low cost, low jitter, high performance clock synthesizer for DVD and other MPEG 2 based applications. Using analog Phase Locked Loop (PLL) techniques, the device accepts

a 27.00 MHz fundamental mode crystal or clock input to produce multiple audio output clocks, a

processor clock, and two 27 MHz clocks. The audio clocks are frequency locked to the 27.00 MHz using our patented zero ppm error techniques, allowing audio and video to track exactly, thereby eliminating the need for large buffer memory.

特性 Features

• Packaged in 16 pin narrow (150 mil) SOIC

• Ideal for AuraVision’s notebook DVD solutions

• Patented zero ppm audio clock error for exact audio clock sampling rates, plus 32x and 256x

clocks of the sampling frequencies

• Selectable audio sampling frequencies support 32, 44.1, 48 and 96 kHz in most DACs

• 27.00 MHz fundamental crystal or clock input

• Selectable processor frequencies

• Two clocks of 27 MHz

• Zero ppm error in all clocks

• 25mA output drive capability at TTL levels

• Advanced, low power, sub-micron CMOS process

• 3.0V to 5.5V operating voltage

• See also the MK2712 for NTSC/PAL clocks
