INFRASTRUCTURE
2SiTime Confidential – Do Not Distribute
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.
SiTime Solution• SiT5356AI-TE-33N0-19.200000

Elite19.2 MHzTCXO
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

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
