DESCRIPTION

· Si50122-A5/A6 is a high-performance, crystal-less PCIe clock generator.

· Generates two 100 MHz PCIe clocks and one 25 MHz LVCMOS clock.

· Compliant with PCIe Gen 1, Gen 2, and Gen 3 specifications.

· Ultra-small footprint (2.0x2.5 mm) with low power consumption.

· Ideal for consumer and embedded applications with limited board space.

FEATURES

· Crystal-less clock generator with integrated CMEMS.

· Two PCIe 100 MHz differential HCSL outputs.

· One 25 MHz single-ended LVCMOS output.

· Supports Serial (ATA) at 100 MHz.

· Low power differential output buffers.

· No termination resistors required for differential output clocks.

· Triangular spread spectrum profile for maximum EMI reduction (Si50122-A6).

· Industrial temperature range: –40 to 85 °C.

· 2.5 V, 3.3 V power supply.

· Small package: 10-pin TDFN (2.0x2.5 mm).

· Si50122-A5 does not support spread spectrum outputs.

· Si50122-A6 supports 0.5% down spread outputs.
