HDMI switch IC handles four inputs

The PS461 HDMI switch has four receivers and one transmitter, enabling TVs to select from among four HDMI inputs. The 100-pin TQFP-packaged chip takes less than 800 mW and has nonvolatile memory for four HDMI or DVI EDIDs (extended display identification data).

The IC can preauthenticate all four HDMI inputs using HDCP (high-bandwidth digital-content protection) cipher engines and an encryption key, reducing delay to less than 1 s when switching between inputs. It supports HDMI 1.4a, has adaptive receiver equalization, and supports up to WUXGA 1080p with component depth of 8/10/12 bits/color. ($1.55 ea/high volume — available now.)
