Standard Specifications

Overall Frequency Stability

Operating Temperature Range

Supply Voltage (Vcc)

± 50, 25, 20 PPM over Operating Temperature Range

0 to +70 C is standard, but can be extended to 40 to +85°C for certain frequencies

3.3 volts ± 10% standard, but 5.0 volts or 2.5 volts also available

50 mA typical, 75 mA maximum

Supply Current (Icc)

Jitter

Output Load

Enable/Disable Option (E/D)

6 pS RMS maximum, from 12 kHz to 20 MHz from carrier

Output must be terminated into 50 ohms to (Vcc - 2.0 V). See Test Circuit 10 and Note 1.

Output enabled when Pin #2 is open or at CMOS Logic “1”;

Output disabled when Pin #2 is at CMOS Logic “0”.

Control Voltage Range (CVR)

Pullablity over CVR

Linearity

0.5 to 4.5 volts: 5.0 V Supply; 0.0 to 3.3 volts: 3.3 V Supply; 0.0 to 2.5 volts: 2.5 V Supply

± 50 PPM. Consult factory for > 50 PPM.

± 20% (Consult factory for ± 10%)

Symmetry

Tr & Tf

Logic “1”

45/55% to 55/45% at 50% of Vcc level (see Waveform 2)

1.0 nS max (20 to 80%)

Vcc - 1.025 volts minimum

Output Waveform

PECL with Differential Output

Logic “0”

Vcc - 1.620 volts maximum

Note 1: In the typical PECL 100K logic output Voh is 2.35 volts and Vol is 1.60 volts at 3.3 Vcc. The center voltage of the PECL is therefore1.975 volts.

If a 50 resistor is placed between the output and Vcc – 2 volts (1.3 volts), the current through the resistor is (1.975 – 1.3) / 50 = 13.5 mA.

The same load can be simulated by a resistor of 147 1% ohms to ground (1.975 / 0.0135 = 146.29 ohms). If additional load current is placed

on the output, its load current must be subtracted from the 13.5 mA to calculate a new load resistor. Using similar calculations, use 274 ± 1%

ohms to ground for 5.0V operation.
