The AD9554-1BCPZ is a quad digital phase-locked loop (DPLL) clock translator designed for multiservice line card applications. It features four reference inputs that can be single-ended or differential, and a 4x4 crosspoint that allows any reference input to drive any PLL. The device supports input reference frequencies from 2 kHz to 1000 MHz and provides four differential clock outputs configurable as HCSL, LVDS-compatible, or LVPECL-compatible.
The digital PLL architecture includes programmable 18-bit integer and 24-bit fractional feedback dividers, programmable loop bandwidths from 0.1 Hz to 4 kHz, and a 20-bit programmable input reference divider. Reference validation and frequency monitoring provide 2 ppm accuracy. The device supports auto/manual holdover and reference switchover, with smooth reference switchover that minimizes disturbance on output phase.
The AD9554-1BCPZ supports Telcordia GR-253 jitter requirements for SONET/SDH systems up to OC-192, ITU-T G.8262 synchronous Ethernet slave clocks, and ITU-T G.823, G.824, G.825, and G.8261 standards. It also supports GR-1244 Stratum 3 stability in holdover mode and adaptive clocking for OTN mapping/demapping applications.
The device operates from a 1.4V to 2.625V supply and is rated for industrial temperature range from -40°C to 85°C. It is available in a 56-lead LFCSP package measuring 8mm x 8mm, designed for surface mount assembly.
The input reference frequency range is 2 kHz to 1000 MHz.
The output frequency range is 430 kHz to 941 MHz.
The four differential outputs are configurable as HCSL, LVDS-compatible, or LVPECL-compatible.
The operating temperature range is -40°C to 85°C (industrial temperature range).
The AD9554-1BCPZ is available in a 56-lead LFCSP package measuring 8mm x 8mm, designed for surface mount assembly.
The supply voltage range is 1.4V to 2.625V.
The AD9554-1BCPZ has four digital PLLs and four reference inputs, with a 4:4 input-to-output ratio.
