What Stands Out
Product Details
- 【Description】The Si5351 is an I2C configurable clock generator ideal for cost-sensitive applications where replacement crystal oscillators, VCXOs, phase-locked loops (PLI) and fan-out buffers are available. Based on the PLL/VCO + high-resolution multi-synchronous decimal divider architecture, the Si5351 can produce an output with any frequency error of 0ppm on each of its up to 160MHZ.
- 【Feature】Generate up to 8 non-integer correlated frequencies in the 8KHz-160MHz range. 12C User-defined configuration. Precise frequency synthesis at each output (0ppm error). High linear VCX0 Optional Clock Input (CLKIN). Low output cycle jitter :100ps pp. Optional configurable spread spectrum at each output. Operates at a low cost, fixed frequency :25 or 27MHz. Static phase offset is supported. Programmable rise/fall time control. No burr frequency change.
- 【Specification】Separate power pins: ① Core VDD: 2.5V or 3.3V. ② Output VDDO: 1.8/2.5V or 3.3V. Superior PSRR eliminates external power filtering. Very low power consumption. Adjustable output - Output delay. Load PCIE 1st generation standard. Supports HCSL compatible swing. Supply voltage: DC3.3-5V.
- 【Pin Definition】SDA: Data pin. SCL: clock pin. VIN:CC. GND: Ground. Pin 0: Clock signal output channel 0. Pin 1: Clock signal output channel 1.
- 【Application】HDTV, DVD/ Blu-ray, set-top box. Residential gateway. Audio/video equipment, games. Network/Communication. Printers, scanners, projectors. Server, Storage. X0 substitution.
