■ 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
■ Ultra short lead time
■ Ideal for Set-top Box, DTV, DVD-R, instrumentation, low bandwidth analog PLL,

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).
