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

Short-form specification — The data in a short-form specification is extracted from a full data sheet with the same type number and title. For detailed information see
the relevant data sheet or data handbook.
Limiting values definition — Limiting values given are in accordance with the Absolute Maximum Rating System (IEC 60134). Stress above one or more of the limiting
values may cause permanent damage to the device. These are stress ratings only and operation of the device at these or at any other conditions above those given
in the Characteristics sections of the specification is not implied. Exposure to limiting values for extended periods may affect device reliability.
