Electrical Characteristics

Notes:

SiTime Corporation

Rev. 0.60

■

■ Any frequency between 1 MHz and 80 MHz with 6 decimal places of accuracy

■ 100% pin-to-pin drop-in replacement to quartz based VCXO

■ Frequency stability as low as ±10 PPM

■ Widest pull range options from ±25 PPM to ±1600 PPM

■ Superior pull range linearity of <= 1%, 10 times better than quartz

■ LVCMOS/LVTTL compatible output

■ Three industry-standard packages: 3.2 mm x2.5 mm (4-pin), 5.0 mm x 3.2 mm (6-pin),

■ Outstanding siicon reliability of 2 FIT (10x improvement over quartz-based devices)

■ Ideal for telecom clock synchronization, instrumentation, low bandwidth analog PLL,

1. Initial tolerance is measure at Vin = Vdd/2

2. Absolute Pull Range (APR) is defined as the guaranteed pull range over temperature and voltage.

3. APR = pull range (PR) - frequency stability (F_stab) - Aging (F_aging)

4. All electrical specifications in the above table are measured with 15pF output load. Contact SiTime for higher drive options.

Conact SiTime for any other voltage support between 2.5V and

3.3V

Vdd = 1.8 V, Voltage at which maximum deviation is guaranteed.

Vdd = 2.5 V, Voltage at which maximum deviation is guaranteed.

Vdd = 2.8 V, Voltage at which maximum deviation is guaranteed.

Vdd = 3.3 V, Voltage at which maximum deviation is guaranteed.

Voltage at which miminum deviation is guaranteed.

For the voltage control pin

Contact SiTime for 16 kHz and other high bandwidth options

No load condition, f = 20 MHz, Vdd = 2.5 V, 2.8 V or 3.3 V

No load condition, f = 20 MHz, Vdd = 1.8 V

All Vdds, ST = GND, output is Weakly Pulled Down

All Vdds

Vdd = 1.8, 2.5, 2.8 or 3.3 V, 10% - 90% Vdd level

OH = -7 mA, IOL = 7 mA, (Vdd = 3.3 V)

IOH = -4 mA, IOL = 4 mA, (Vdd = 2.8 V and Vdd = 2.5 V)

IOH = -2 mA, IOL = 2 mA, (Vdd = 1.8 V)

For the OE/ST pin if available

f=80 MHz, all Vdds. For other freq, T_oe = 100 ns + 3 cycles

Measured from the time ST pin crosses 50% threshold

f = 75 MHz, Vdd = 2.5 V, 2.8 V or 3.3 V

f = 75 MHz, Vdd = 1.8 V

f = 75 MHz, Integration bandwidth = 12 Mhz to 20 MHz, all Vdds
