840001I-25
840001I-25 is LVCMOS/LVTTL Clock Generator manufactured by Renesas.
DESCRIPTION The 840001I-25 is a General Purpose Clock Generator and a member of the family of high performance devices from IDT. The 840001I-25 can accept frequency from a 22.4MHz to 170MHz and generate a 22.4MHz to 170MHz output. The 840001I-25 has excellent phase jitter performance, from 637k Hz - 10MHz integration range. The 840001I-25 is packaged in a small 8-pin TSSOP, making it ideal for use in systems with limited board space. FEATURES - One LVCMOS/LVTTL output, 15Ω output impedence - Output frequency range: 22.4MHz - 170MHz - VCO range: 560MHz to 680MHz - RMS phase jitter @ 125MHz (637k Hz - 10MHz): 0.36ps (typical) - Full 3.3V or 2.5V operating supply - -40°C to 85°C ambient operating temperature - Available in lead-free (Ro HS 6) package MONLY USED FREQUENCY TABLE SEL2 0 0 0 0 1 1 1 1 SEL1 0 0 1 1 0 0 1 1 SEL0 0 1 0 1 0 1 0 1 Inputs M Divider 25 10 4 5 10 5 4 10 N Divider 25 25 25 25 10 5 4 25 REF_IN (MHz) 25 62.5 156.25 125 62.5 125 156.25 62.5 Output Frequency (MHz) Q 25 25 25 25 62.5 125 156.25 25 (default) BLOCK DIAGRAM REF_IN Pullup Phase Detector 560-680MHz ÷4 ÷5 ÷10 ÷25 M ÷4, ÷5, ÷10, ÷25 SEL_[0:2] Pullup PIN...
