PON – Optical Line Terminal (OLT)

Why SiTime MEMS vs. Quartz? • Better dynamic performance than quartz:

• Fast Temperature transients – 100’s times better than quartz

• Vibration sensitivity ~80 times better than quartz.

• SiTime had 0 packet loss during test• All competitors dropped packets and failed

tests.

PON Multiple Dwelling Unit (MDU)Why SiTime?

• Better dynamic performance than quartz:• G-sensitivity/Vibration: ~80 times better than quartz

• No packet loss in Hand-slapping Test of MDU. Quartz causes unacceptable packet loss (>10-8 BER)

• Customer was so impressed by SiTme performance, they referred us to Broadcom (G.FAST chipset)

SiTime Solution• SiT9365-156.25 MHz• Nextgen BRCM chipset will require 70.656 MHz • differential DE Oscillator

Precision GPS Module for Automotive

Why SiTime MEMS with I2C?• Better dynamic performance than quartz:

• G-sensitivity/Vibration ~ 80 times better than quartz• Temperature transients ~ 100’s times better than quartz

• I2C Frequency Control to .07 ppb resolution• Allows simpler algorithm to align oscillator phase with

GPS time. Lowers solution cost
