SiT1408B
SiT1408B is Active Resonator Drop-In Replacement manufactured by SiTime.
Features
- No load capacitors required
- No motional series resistance (ESR) pensation
- No negative resistance testing
- Guaranteed oscillator startup under all conditions
- One active resonator can drive up to two clock inputs
- All-inclusive frequency stability as low as ±20 ppm over extended temperature range (-40°C to 85°C). Refer to Si T1418 and Si T1420 for high temperature options
- Any frequency between 1 MHz and 110 MHz accurate to 6 decimal places
- Qualify just one device with 1.62 V to 3.63 V continuous supply voltage option
- Industry best G-sensitivity of 0.1 ppb/g
- Low power consumption of 3.5 m A typical at 1.8 V
- LVCMOS patible output
- Industry-standard packages: 2.5 x 2.0, 3.2 x 2.5 mm x mm
- Ro HS and REACH pliant, Pb-free, Halogen-free and Antimony-free
Conditions for Drop-In-Replacement
- Si T1408 is designed to work with non-wireless MCUs except for BLE which is supported
- Si T1408 is footprint patible to 4-pad SMD Xtal resonators with electrically grounded pin 2 and 4
- MCU/µC supports external oscillator mode
- MCU/µC supports GPIO output function on XTAL1 pin
(Figure 18) and able to drive ~6 m A across 1.8 V to 3.3 V VDD continuous voltage
Applications
- Ideal for DSC, DVC, DVR, IP CAM, Tablets, e-Books, SSD, GPON, EPON, etc.
- Ideal for high-speed serial protocols such as: USB: SATA, SAS, Firewire, 100M / 1G / 10G Ethernet, etc.
