Smallest Voltage Controlled MEMS Oscillator (VCMO)
Electrical Characteristics
Notes:
1. Absolute Pull Range (APR) is defined as the guaranteed pull range over temperature and voltage.
2. APR = pull range (PR) - frequency stability (F_stab).
■The world’s only VCMO with programmable pull range: ±60 PPM, ±120 PPM, ±240 PPM
■Typical pull range linearity of 0.06%
■1-110 MHz frequency range
■LVCMOS/LVTTL compatible output
■Typical power consumption of 6.1 mA in active mode
■Typical VCMO tuning voltage: 0 V to 1.85 V for all Vdds
■Four industry-standard 4-pin packages: 2.5 x 2.0, 3.2 x 2.5, 5.0 x 3.2, 7.0 x 5.0 mm
■All-silicon timing device with outstanding reliability of 2 FIT (10x improvement over
quartz-based devices), enhancing system MTBF
■Ultra short lead time
■Ideal for Set-top Box, DTV, DVD-R, instrumentation, low bandwidth analog PLL,
networking and communications
