Micrel Launches New Configurable Four Output, Low Jitter Crystal-less™ Clock Generator

SAN JOSE, CA--(Marketwired - Mar 13, 2014) - Micrel, Inc. (NASDAQ: MCRL), an industry leader in high performance linear and power solutions, LAN and timing and communications solutions, today introduced the DSC400, a four output crystal-less™ clock generator. This is the first Micrel MEMS-based timing product launch which utilizes Micrel's proven PureSilicon™ MEMS technology to provide excellent jitter and stability while incorporating additional device functionality. The device targets a broad range of applications including communications and networks; Ethernet 1G, 10GBASE-T/KR/LR/SR, and FCoE; storage area networks, FC, SATA, SAS, FTTH EPON, 10G-EPON, GPON and 10G-PON; HD/SD/SDI video and surveillance; automotive; media and video and embedded and industrial. The DSC400 is available in volume quantity with pricing starting at $3.90. For samples, please contact Micrel sales:

"The DSC400 is a Crystal-less™ multi-output clock generator that, unlike other clock generators on the market, does not require an external crystal to operate. Instead, it relies on an integrated MEMS resonator that interfaces with internal PLLs," noted Rami Kanama, vice president, timing and communications business group, Micrel. "This technology enhances performance and reliability by enabling tight frequency stability over a wide temperature range. In addition, it has high resistance to shock and vibration which slows the aging rate and translates into much improved product life in the system."

The device features low RMS phase jitter of less than 1 ps (typ) and high stability with +/-25 ppm and +/-50 ppm options. The DSC400 also offers high supply noise rejection of -50 dBc and generates four outputs. Each output maybe independently configured to be in LVPECL, LVDS, HCSL or LVCMOS format. With a wide frequency range of 2.3 MHz - 460 MHz, the device has excellent shock and vibration immunity (qualified to MIL-STD-88), high reliability and a wide supply range of 2.24 to 3.6V. The solution is RoHS compliant and is qualified to MIL-STD-883 and automotive AEC-Q100. It has a wide temperature range; (-20degC to 70degC for extended commercial and -40degC to 85degC for industrial) and is offered in a 20 QFN footprint (5mm x 3.2mm) package size.
