Manufacturer of High Quality Frequency Control Products

PE3345B PECL Series

4 Pad Leadless Surface Mount Clock Oscillator

–

10.00 MHz 170.00 MHz

Differential PECL Output with Enable/ Disable Function

See PE1145T for higher frequencies

Standard Specifications

Overall Frequency Stability

± 50 PPM, ± 25 PPM, ± 20 PPM over Operating Temperature Range

Operating Temperature Range 0 to +80 C is standard, but can be extended to 40 to +85°C for certain frequencies

Supply Voltage (Vcc)

Supply Current (Icc)

Jitter

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

60 to 70 mA typical, 90 mA maximum for 70 MHz. For < 70 MHz, consult factory

1 pS RMS maximum, from 12 kHz to 20 MHz from carrier for ³ 70 MHz. For < 70 MHz, consult factory

Output must be terminated into 50 ohms to (Vcc - 2.0 V). See Test Circuit 5 and Note 1.

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

Output Load

Enable/Disable Option (E/D)

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

Symmetry

Tr & Tf

Logic “1”

45/55% to 55/45% at 50% of Vcc level standard, tighter symmetry available

Output Waveform

PECL with Differential Output

(see Waveform 2)

1.0 nS max (20 to 80%) for 70 MHz. For < 70 MHz, consult factory

Vcc - 1.025 volts minimum

Vcc - 1.620 volts maximum

Logic “0”

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 ohm 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.

Special Specifications (choose all that apply)

Frequency Stability

E: Extended Operating Temperature Range (- 40 to +85 C)

F: 47.5 /52.5% Symmetry at 50% of Vcc

V: Supply Voltage of 3.3 volts ± 10%

45 = ± 50 PPM

44 = ± 25 PPM

20 = ± 20 PPM

W: Supply Voltage of 2.5 volts ± 5%

Y: Supply Voltage of 5.0 volts ± 10%

Consult factory for available frequencies and specs. Not all options available for all frequencies. A special part number may be assigned.

Frequency Stability is inclusive of frequency shifts due to calibration, temperature, supply voltage, shock, vibration and load
