CDC536DB

The Texas Instruments CDC536DB is a high-performance PLL clock driver featuring a 3.3V core supply voltage and capable of distributing one clock input to six outputs. It operates at frequencies up to 100MHz and offers frequency options of 1/2x, 1x, and 2x the input frequency. The device is designed for low-output skew and low jitter, making it suitable for synchronous DRAM and high-speed microprocessor applications.

This clock driver utilizes TTL-compatible inputs and LVTTL outputs, designed to drive 50-ohm parallel-terminated transmission lines. It features a phase-lock loop (PLL) with bypass functionality for precise alignment of output signals to the input clock. The CDC536DB operates within a temperature range of 0°C to 70°C and is packaged in a 28-SSOP surface-mount configuration.

Key electrical characteristics include an additive RMS jitter of 200 fs (typical) and an output skew of 500 ps (typical). The device supports a voltage range of 3V to 3.6V. Its design incorporates distributed VCC and ground pins to minimize switching noise, and it uses a state-of-the-art EPIC-II B BiCMOS process for reduced power dissipation.
