- Part Number:
- MK2745-21SLF
- Manufacturer:
- IDT, Integrated Device Technology Inc
- Ventron No:
- 2983238-MK2745-21SLF
- Description:
- IC CLK SOURCE DVD/MPEG 16-SOIC
- ECAD Model:
-
- Datasheet:
- MK2745-21SLF
Description
The MK2745-21 is a low-cost, low-jitter, high-performance clock synthesizer designed for DVD and MPEG 2 applications. It utilizes analog Phase-Locked Loop (PLL) techniques to generate multiple audio output clocks, a processor clock, and other fixed clocks from a 27 MHz fundamental mode crystal or clock input. The audio clocks are frequency-locked to the 27 MHz using patented zero ppm error techniques, ensuring precise tracking between audio and video.
Features
Packaged in a 16-pin narrow (150 mil) SOIC
Ideal for LuxSonor's DVD solutions
3.3V upgrade to the MK2744
Patented zero ppm audio clock error for 256x and 384x sampling rates
Selectable audio sampling frequencies (32, 44.1, and 48 kHz)
27 MHz fundamental crystal or clock input
Eight selectable processor frequencies
Fixed clocks of 27 and 24.576 MHz
Zero ppm in all clocks
25 mA output drive capability at TTL levels
Advanced, low-power, sub-micron CMOS process
Operating voltage of 3.0 V to 5.5V
Applications
DVD players
MPEG 2-based applications
Set-top boxes
