Real-Time Clock/Calendar -- MCP79510
from Microchip Technology, Inc.

The MCP79510 SPI RTCC is highly integrated with memory and advanced features normally found in higher priced devices. By starting with a basic real-time clock, digital trimming was added for higher accuracy, a battery switchover for backup power, a timestamp to log power failures and three types of... [See More]

ITU-T G.8262 Synchronous Ethernet Jitter-Attenuating Clock Multiplier -- Si5328B-C-GM
from Silicon Labs

Description: The Si5328 is a jitter-attenuating precision clock multiplier for Synchronous Ethernet applications requiring sub 1 ps jitter performance and ultra-low loop bandwidth. When combined with a low-wander, lowjitter reference oscillator, the Si5328 meets all of the wander, MTIE, TDEV, and... [See More]
