Texas Instruments Introduces High-Performance Clock Synthesizer and Jitter Cleaner

Texas Instruments (TI) today announced a clock synthesizer and jitter cleaner with the industry's lowest phase noise and jitter. The solution offers higher performance and better design flexibility to meet the increasing demands of customers in this area, such as 2.5G/3G wireless base stations, data communications, medical imaging and measurement testing. (For more information, please visit: )

The CDCM7005 provides high precision and stable frequency, making it ideal for signal chain devices such as analog-to-digital converters (ADCs), digital-to-analog converters (DACs), digital upconverters (DUCs), and digital downconverters (DDCs). The device also features industry-lowest phase noise of -219 dBc/Hz (PLL quality factor), 162 fs for LVPECL, and minimum phase jitter performance of 232 fs for LVCMOS, and a maximum output offset of 20 ps. This superior performance not only undersamples data converters such as ADCs at higher input frequencies, but also provides the highest signal-to-noise ratio.

The CDCM7005 has features that maximize design flexibility, including Serial Peripheral Interface (SPI) logic for programming and independent support control. The device synchronizes the voltage controlled crystal oscillator (VCXO) frequency up to 2.2 GHz (LVPECL) with either of the two reference clocks to provide a clean, high frequency clock output. These outputs can be divided by a ratio of 1, 2, 3, 4, 6, 8, or 16 and provide output selection at the LVCMOS and LVPECL levels.

The solution also has other very useful features, including a device bias voltage (VBB) pin that provides the correct voltage for a single-ended VCXO, eliminating the need for external resistors and significantly simplifying the product design process. . In addition, the CDCM7005 supports frequency hold mode and fast frequency lock for auto-protection and higher system redundancy.

PVC Resin

PVC Resin is easy to process, and can be processed by molding, lamination, injection molding, extrusion, calendering, blow molding and other hollow methods. Polyvinyl chloride is mainly used to produce artificial leather, film, wire sheath and other plastic soft products, but also can produce plates, doors and windows, pipes and valves and other plastic hard products.

PVC Resin usually inculde carbide based and ethylene based. K66-K68 PVC RESIN, K59-K55 PVC RESIN, K71-K73 PVC RESIN. PVC RESIN SG5, PVC RESIN SG3, PVC RESIN SG8.

According to the different application scope, PVC can be divided into: general-purpose PVC resin, high polymerization degree PVC resin, and cross-linked PVC resin. General-purpose PVC resin is formed by the polymerization of vinyl chloride monomer under the action of initiator; high degree of polymerization PVC resin refers to the resin polymerized by adding chain extender to the vinyl chloride monomer polymerization system; cross-linked PVC resin is A resin polymerized by adding a crosslinking agent containing diene and polyene to the vinyl chloride monomer polymerization system.
According to the method of obtaining vinyl chloride monomer, it can be divided into Calcium Carbide method, ethylene method and imported (EDC, VCM) monomer method (the ethylene method and imported monomer method are commonly referred to as ethylene method).
According to the polymerization method, polyvinyl chloride can be divided into four categories: suspension polyvinyl chloride, emulsion polyvinyl chloride, bulk polyvinyl chloride, and solution polyvinyl chloride. Suspension process polyvinyl chloride is the largest variety in output, accounting for about 80% of the total output of PVC. Suspension method PVC is divided into six models according to absolute viscosity: XS-1, XS-2--XS-6; XJ-1, XJ-2--, XJ-6. The meaning of each letter in the model: X-suspension method; S-loose type; J-compact type.
