PLL1705 Clock Generator | CDCE906 Clock Synthesizer/Multiplier/Divider

PLL1705 - 3.3 V Dual PLL Multi-Clock Generator

The PLL1705 is a multi-clock generator and is a dedicated solution for providing the audio clock with zero parts per million (PPM) error on the outputs, a necessary feature to keep the audio synchronized with the video. The device provides space savings by eliminating many external components and works from a 27-MHz input clock found in many video applications and derives the necessary audio clock used by TI's low power stereo audio codecs, like the TLV320AIC33.

CDCE906 - Programmable 3-PLL Clock Synthesizer/Multiplier/Divider

The CDCE906 device has extremely low jitter of 60 psec and zero PPM offset clock generation for most A/V frequencies and applications. This is critical for higher-end video systems and for DaVinci™ platforms used to support extensive system architectures and features where additional clocking frequencies and fanout are required. Because of its low power, high performance and high levels of integration, the CDCE906 is a very cost-effective and compelling solution for consumer applications such as HDTV, Set top box and DVD.

Flexibility

• 3-PLL programmable clock multiplier supports up to 6 different clocks from one source
• Supports 4 audio outputs
• Multiple Sampling Frequencies: f_S = 32, 44.1, 48, 64, 88.2, 96 kHz
• 3.3-V Single Power Supply

Leading Performance

• Period Jitter: 60psec
• Optimized on-board EMI reduction
• Zero PPM offset clock generation ensures synchronization of audio and video
