Abstract

The present application provides a modem chip and an application processor including the modem chip. The modem chip is in communication with the radio frequency chip and includes a digital interface configured to receive data including a plurality of samples from the radio frequency chip based on the digital communication. A logic block generates a frame synchronization signal based on a clock signal in the modem chip, provides the generated frame synchronization signal to the digital interface, and receives the plurality of samples in synchronization with the frame synchronization signal.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to Korean Patent Application No. 10-2016-0109551 filed in the Korean Intellectual Property Office on Aug. 26, 2016, the entire disclosure of which is hereby incorporated by reference. technical field [0003] The present disclosure relates to a modem chip, and more particularly, to a modem chip performing digital communication with a radio frequency (RF) chip, an application processor including the modem chip, and an operating method of the modem chip. Background technique [0004] Recently, as a large amount of data is transmitted or received using a smartphone or the like, the amount of data transmitted or received between the RF chip and the modem chip is also increasing. Various communication methods between the RF chip and the modem chip have been proposed. For example, a method of transmitting and receiving I, Q analog signals between an RF chip and a modem chip by using a digita...
