Hybrid data transmission circuit

A data transmitter having a parallel-to-serial conversion function is supplied with a clock by a PLL circuit unit. In the PLL circuit unit, a first multiphase clock supplied to a first parallel-to-serial conversion circuit is generated and output by a multiphase VCO circuit, while a second multiphas...

Zusammenfassung:	A data transmitter having a parallel-to-serial conversion function is supplied with a clock by a PLL circuit unit. In the PLL circuit unit, a first multiphase clock supplied to a first parallel-to-serial conversion circuit is generated and output by a multiphase VCO circuit, while a second multiphase clock supplied to a second parallel-to-serial conversion circuit is generated and output by a multiphase clock generator. The multiphase clock generator generates the second multiphase clock based on the clock output from the multiphase VCO circuit.
