TI Korea (CEO Kent Jeon, www.ti.com/ww/kr ) April 4, 2012 – TI has expanded its high-performance clock buffer portfolio by launching two new general-purpose clock buffer families. The CDCLVC1310 LVCMOS clock buffer provides an industry-leading phase noise floor of -169 dBc/Hz in crystal mode. The LMK00101/05 complements the family with flexible output voltage level setting capabilities. The jitter characteristics of the LMK00301/04/06/08 differential end families are ultra-low at 51 fs (femtoseconds).

In response to modern communication systems that require strict system jitter budgets as data transfer speeds increase, these devices provide low jitter, skew, and built-in signal-level translators. These new product families support applications such as networking and data communications, medical imaging, test and measurement, and radar.

Features and advantages of CDCLVC1310, LMK00101/105
• Ultra-low system jitter performance (25fs) and superior noise floor characteristics in crystal mode support enhanced system communication link and signal-to-noise (SNR) performance.
• Universal input architecture (LVPECL, LVDS, HCSL, SSTL, LVCMOS) and built-in voltage level and signal translators reduce board space by 50%
• General-purpose I/O supply voltages (1.5V, 1.8V, 2.5V, 3.3V) simplify system design and reduce Bill of Material (BOM) costs by up to 50%

Features and advantages of LMK0030x (LMK00301/04/06/08)
• An additional 51fs RMS jitter at 156.25MHz (12kHz–20MHz) provides more than twice the flexibility of the closest competing devices, supporting enhanced system link performance.
• A general-purpose output architecture featuring built-in voltage levels and signal translators eliminates the need for interface logic and external components, saving over 50% of board space.
• Configurable output clock reduces customer R&D device evaluation costs by more than 50%

TI offers a vast portfolio of complementary devices capable of optimizing high-speed signal chains. Some devices that complement these clock buffers are as follows:
• Clock Generator: LMK03806, CDCM61001
• High-speed data converters: DAC3484, ADS4149, ADC12D1800RF product family
• DSP (Digital signal processor): TMS320C66x.
