描述 Description

The 8T49N028 is a low RMS phase jitter Clock Synthesizer with selectable internal crystal oscillator or external clock references and eight outputs, configurable as either LVDS, LVPECL or High Impedance.

特性 Features

• Fourth Generation FemtoClock NG PLL technology
• Eight selectable LVPECL or LVDS outputs (bank selectable, two output channels per bank)
• CLK, nCLK input pair can accept the following differential input levels: LVPECL, LVDS, HCSL
• FemtoClock NG VCO Range: 1.92GHz - 2.5GHz
• Bank A and B output frequencies are mux selectable from internal crystal oscillator, reference clock input, output divider A or output divider B
• Clock from OUTPUT DIVIDER A, RMS phase jitter at 156.25MHz(12KHz - 20MHz): 225fs (typical)
• Clock from OUTPUT DIVIDER B, RMS phase jitter at 156.25MHz(12KHz - 20MHz): 219fs (typical)
• Clock from OUTPUT DIVIDER B, RMS phase jitter at 156.25MHz(10kHz - 1MHz): 165fs (typical) Full 2.5V or 3.3V power supply
• Full 2.5V or 3.3V power supply
• I2C programming interface
