CY27410FLTXI

Product Overview

• Product Overview

  CY27410FLTXI is a standard-performance programmable clock generator with four independent fractional PLLs, which generates any frequency with a zero-ppm synthesis error. Each PLL is followed by a set of four independent dividers to generate four different frequencies from a single PLL. All four dividers are synchronized to generate phase-aligned clock outputs with minimal skew. The PLLs also support the spread-spectrum feature to reduce EMI. PLL 1 has VCXO functionality to achieve ppm granularity of output frequency. The CY27410 accepts a crystal clock or a single-ended/differential reference clock. The device supports up to 12 outputs, divided into two banks with six outputs each. Four outputs of PLL 1 and PLL 2 are multiplexed to output Bank 1, and four clock outputs of PLL 3 and PLL 4 are multiplexed to output Bank 2. The 12 outputs of the two banks are configurable as eight differential outputs, 12 single-ended outputs, or a combination of differential and single-ended outputs.
