ICS552ARI-01

DATASHEET ICS552A-01 OSCILLATOR, MULTIPLIER, AND BUFFER WITH 8 OUTPUTS Description • Power-down and Tri-state modes 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 IDT’s 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: 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 mA output drive capability at TTL levels Advanced, low power, sub-micron CMOS process 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 C mode) Features (all) • Use with 25 MHz crystal for networking • Use with 27 MHz crystal for MPEG • • • • ICS552A-01 (for A and C modes) Packaged as 20-pin SSOP (QSOP) Pb-free packaging available Operating voltages of 3.0 V to 5.5 V Industrial temperature available • Input frequency of 10.0 to 27.0 MHz • Provides 8 low-skew outputs (
