ICS552A-01 Datasheet | ICST

.. Oscillator, Multiplier, and Buffer with 8 Outputs Description The ICS552A-01 produces 8 low-skew copies of the multiple input clock or fundamental, parallel-mode crystal. Unlike other clock drivers, these parts do not require a separate oscillator for the input. Using ICS’ patented Phase-Locked Loop (PLL) to multiply the input frequency, it is ideal for generating and distributing multiple high-frequency clocks. This is a single chip used for 3 different applications: 1) ICS552A-01 (A mode) - an Oscillator mutiplier 2) ICS552A-01 (B mode) - a Dual 1:4 buffer 3) ICS552A-01 (C mode) - a 1:8 Oscillator buffer ICS552A-01 (for B mode) - Up to 200 MHz clock input/output at 3.3 V - Low skew of 250 ps maximum for any bank of four - Inputs can be connected together for a 1 to 8 buffer with 250 ps skew between any outputs - - - - Non-inverting buffer mode Ideal for clock networks Output Enable mode tri-states outputs Full CMOS output swing with 25 m A output drive capability at TTL levels - Advanced, low power, sub-micron CMOS process ICS552A-01 (for C mode) Features (all) - - - - Packaged as 20-pin SSOP (QSOP) Pb-free packaging available Operating voltages of 3.0 V to 5.5 V Industrial temperature available - Use with 25 MHz crystal for networking - Use with 27 MHz crystal for MPEG ICS552A-01 (for A and C modes) Features (specific) ICS552A-01 (for A mode) - Input frequency of 10.0 to 27.0 MHz - Provides 8 low-skew outputs (<250 ps) - Output clock duty cycle of 40/60 at 3.3...
