P r e l i m i n a r y D a t a s h e e t M675S02 SIGE SINGLE FREQUENCY VCSO FOUT 4 5 6 VCC The M675S02 is a single frequency/single output SAW-based VCSO for low-jitter clock generation. The SAW (surface acoustic wave) delay line serves as a high-Q resontaor and the low noise SiGe VCSO IC provides a low noise floor and low 1/f phase noise. The combination of the SAW delay line and the custom IC result in very low phase noise and jitter performance. The M675S02 is available in frequencies from 500 to 1000 MHz with a guaranteed minimum pull-range of ±120 ppm. Industry-standard Kvco (VCO Gain) provides full replacement compatibility for most designs. The M675S02 is well suited for phase-locked loop applications, clock and data recovery circuits and other timing applications in telecom and optical fiber networking systems. nFOUT PIN ASSIGNMENT (5 x 7.5mm SMT) M675S02 3 2 CLK_EN GND 1 (Top View) VIN GENERAL DESCRIPTION Figure 1: Pin Assignment Sample of Available Output Frequencies FEATURES ◆ Integrated SAW device VCSO Center Frequencies1 (MHz) ◆ Low phase jitter 0.2ps rms typical for the M675S02 (50kHz to 80MHz) - Design Target Applications 622.0800 SONET/SDH ◆ Output frequencies from 500 to 1000 MHz (Specify center frequencies at time of order) 625.0000 Gigabit Ethernet ◆ Industry-standard Kvco for full compatibility 644.5313 GbE FEC ◆ Differential 3.3V LVPECL output ◆ Single 3.3V power supply 669.3266 ◆ Small 5 x 7.5mm SMT (surface mount) package ◆ Pb-free / Compliant to EC RoHS Directive (RoHS 5/6) SONET/SDH FEC Table 1: Sample of Available Output Frequencies Note 1: Specify VCSO center frequency at time of order BLOCK DIAGRAM M675S02 SAW Delay Line FOUT Phase Shifter nFOUT VIN CLK_EN Figure 2: Block Diagram M675S02 Datasheet Rev 1.0 Revised 07Feb2012 M675S02 SiGe Single Frequency VCSO I n t e g r a t e d D e v i c e Te c h n o l o g y, I n c . ● Netcom Timing ● w w w. i d t . c o m ● t e l ( 7 7 4 ) 3 4 8 - 1 6 0 0 M675S02 SIGE SINGLE FREQUENCY VCSO Preliminary Datasheet PIN DESCRIPTIONS Number 1 Name VIN I/O 2 CLK_EN Input 3 GND Ground 4 5 6 FOUT nFOUT VCC Configuration Description Input Output Frequency control input.
