Pl tronics., Inc. 19013 36th Ave. W, Suite H Lynnwood, WA 98036 USA Manufacturer of High Quality Frequency Control Products PE2245B PECL Series 10 Pad Leadless Surface Mount Clock Oscillator, see PE1145B for 6 Pad Differential PECL Output with or without Enable/ Disable Function All Connor-Winfield EE94-5XX Pinouts Available Standard Specifications Overall Frequency Stability Operating Temperature Range Supply Voltage (Vcc) Supply Current (Icc) Jitter Output Load Enable/Disable Option (E/D) (as applicable) Output Waveform PECL with Differential Output (see Waveform 2) ± 50 PPM, ± 25 PPM, ± 20 PPM over Operating Temperature Range 0 to +80 °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 60 to 70 mA typical, 90 mA maximum for ³ 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 E/D Pin is open or at CMOS Logic “1”; Output disabled when E/D Pin is at CMOS Logic “0”. Symmetry Tr & Tf Logic “1” Logic “0” 45/55% to 55/45% at 50% of Vcc level standard, tighter symmetry available 1.0 nS max (20 to 80%) for ³ 70 MHz. For < 70 MHz, consult factory Vcc - 1.025 volts minimum Vcc - 1.620 volts maximum 10.00 MHz – 170.00 MHz See PE1145T for higher frequencies Note 1: In the typical PECL 100K logic outpu...
