Silicon Laboratories Si51x XO and VCXO Crystal Oscillators

Silicon Laboratories introduced the Si51x XO/VCXO family of crystal oscillators (XOs) and voltage-controlled XOs (VCXOs). The Si512/3 dual-frequency XO devices can replace two discrete XOs and a multiplexer in networking, broadcast video and other applications that use multi-rate SerDes devices and FPGA devices. Si510/511 single-frequency XO is priced from $2.10 to $3.69 (in 10,000-unit quantities). Pricing for the Si514 I2C-programmable XO is $2.71 to $10.23 (in 10,000-unit quantities). Silicon Labs’ Si51x XO/VCXO family is ideal for networking, communications, storage, server, embedded computing and broadcast video systems.
