AD9517-4ABCPZ is a high-performance, low-jitter clock generator chip launched by ADI. It integrates a phase-locked loop (PLL) and a voltage-controlled oscillator (VCO). It is designed for communication, test measurement and data conversion applications that require high-precision clock distribution. The following are its core features and technical parameters:
*** 2 pairs of LVPECL outputs (1.6 GHz, each pair shares a 1-32 divider, channel-to-channel skew <10 ps, additional jitter 225 fs rms).
*** 2 pairs of LVDS outputs (800 MHz, each pair supports cascaded division, additional jitter 275 fs rms, configurable fine delay adjustment).
*** Each LVDS output can be reconstructed into 2 CMOS outputs (250 MHz).
Low jitter design: Sub-picosecond jitter performance ensures high-speed signal integrity, suitable for high-speed ADC/DAC, wireless transceivers and other scenarios.
Integrated 1.6 GHz VCO: Tuning range 1.45 GHz to 1.80 GHz, optional external VCO/VCXO extended to 2.4 GHz.
Automatic/manual reference switching: Supports 1 differential or 2 single-ended reference inputs (LVPECL/LVDS/CMOS, up to 250 MHz), with reference monitoring and redundant switching functions.
Package and power supply: 48-pin LFCSP package, 3.3 V single power supply, extended VCO voltage range up to 5 V.
Temperature range: -40°C to +85°C, suitable for harsh industrial environments.
2. Key application scenarios
Communication infrastructure: 10/40/100 Gb/s network line cards (such as SONET, synchronous Ethernet, OTU2/3/4 forward error correction). Wireless base station clock distribution (supporting high-performance dual-channel IF sampling receivers).
Data conversion system: high-speed ADC/DAC clock driver (such as JESD204B interface device).
DDS (direct digital frequency synthesis), DDC/DUC (digital down/up conversion) module.
Test and measurement: ATE (automatic test equipment), high-precision instrumentation (such as oscilloscope, spectrum analyzer).
III. Additional functions and advantages
Automatic synchronization and phase control: supports automatic synchronization of all output channels at power-on, and provides programmable phase delay adjustment.
Phase lock detection: digital/analog phase lock status monitoring to enhance system reliability.
Evaluation board support: AD9517-4A/PCBZ evaluation board provides a rapid prototyping platform compatible with AD9516/AD9517/AD9518 series.
