The LMK033x8 features two fractional-N frequency synthesisers with integrated VCOs, flexible clock distribution/fanout, and pin selectable configuration states stored in on-chip EEPROM. The device is claimed to generate multiple clocks for various multi-gigabit serial interfaces and digital devices, reduces BOM cost and board area, and improves reliability by replacing multiple oscillators and clock distribution devices.
LMK033x8 clock generators come in a 7 x 7mm QFN package and feature a 1.8, 2.5 or 3.3V output supply across an operating temperature range of -40 to 85°C. The devices are suitable for applications in switches and routers, network and telecom line cards, servers and storage systems and wireless base stations.
TI offers a broad timing portfolio that also includes ultra-low-additive jitter fan-out buffers like the LMK00301 universal differential buffer and the LMK00338 PCI Express Gen-3-compliant high-speed current steering logic buffer, which complement the LMK03328 and LMK03318.
