INTEGRATED CIRCUITS PCK3807A 1:10 LVTTL clock distribution device Product data sheet Supersedes data of 2003 Jun 27 Philips Semiconductors 2004 Aug 27 Philips Semiconductors Product data sheet 1:10 LVTTL clock distribution device PCK3807A • High speed: propagation delay < 3.5 ns (max) • Very low CMOS power levels • TTL compatible inputs and outputs • 1:10 fanout • Maximum output rise and fall times < 1.5 ns • Low input capacitance: 2.5 pF typical • VCC = 2.3 V to 3.6 V • Overvoltage tolerance on inputs • Available in SSOP, TSSOP, SO and QSOP packages • >150 MHz operation DESCRIPTION This low skew clock driver offers 1:10 fan-out. The large fan out from a single input reduces loading on the preceding driver and provides an efficient clock distribution network. The PCK3807A offers low capacitance inputs with hysteresis for improved noise margins. Multiple power and grounds reduce noise. Typical applications are clock and signal distribution. The PCK3807A operates from a single 2.5 V or 3.3 V supply voltage and over the full industrial temperature range of –40 °C to +85 °C. FEATURES • Low output skew < 120 ps (max) • Very low duty cycle distortion < 200 ps (max) for VCC = 2.5 V ORDERING INFORMATION PACKAGES TEMPERATURE RANGE ORDER CODE DRAWING NUMBER 20-Pin Plastic SO –40 °C to +85 °C PCK3807AD SOT163-1 20-Pin Plastic SSOP –40 °C to +85 °C PCK3807ADB SOT339-1 20-Pin Plastic TSSOP –40 °C to +85 °C PCK3807APW SOT360-1 20-Pin Plastic SSOP (QSOP) –40 °C to +85 °C PCK3807ADS SOT724-1 FUNCTIONAL BLOCK DIAGRAM PIN CONFIGURATION O1 O2 O3 O4 O5 IN 1 20 VCC GND 2 19 O10 O1 3 18 O9 VCC 4 17 GND O2 5 16 O8 GND 6 15 VCC O3 7 14 O7 VCC 8 13 GND O4 9 12 O6 GND 10 11 O5 IN O6 SW00986 O7 PIN DESCRIPTION O8 Symbol IN O9 O1 to O10 O10 SW00985 2004 Aug 27 2 Pin Description 1 3, 5, 7, 9, 11, 12, 14, 16, 18, 19 GND 2, 10, 13, 17 VCC 20 Clock input Clock outputs Ground Supply voltage Philips Semiconductors Product data sheet 1:10 LVTTL clock distribution device PCK3807A ABSOLUTE MAXIMUM RATINGS1 DESCRIPTION MIN MAX UNIT 2 Terminal voltage with respect to GND –0.5 +4.6 V VTERM3 Terminal voltage with respect to GND –0.5 +7 V VTERM4 Terminal voltage with respect to GND –0.5 VCC +0.5 V Tstg Storage temperature –65 +150 °C IO DC output current –60 +60 mA SYMBOL VTERM NOTES: 1.
