TOSLINK Output circuit - Optical Audio

IC2501 6-710-429-01 TC7WP3125FK - 1.5V to 3.3V levelshifter

optical audio path[edit]

generic:

  • from RSX the digital audio is 1.5V level (SPO0/RS_SPDO)
  • IC2501 6-710-429-01 TC7WP3125FK - 8pin IC is a 1.5V>3.3V level shifter
  • IC2409 TOSLINK takes 3.3V level signal input
  • IC2409 TOSLINK takes 5V VCC

COK-001 / CECHAxx + CECHBxx[edit]

goes from RSX BGA-pad AV18 (SPO0) to R2051 (22Ω) -> RS_SPDO // RS_SPDO goes to pin 2 of IC2501 (TC7WP3125FK)
RS_SPDO_33 comes from pin 7 of IC2501 (TC7WP3125FK)
RS_SPDO_33 goes to layerhole to R2412 and goes directly to IC2409 (TOSLINK connector)

COK-002 / CECHCxx + CECHExx[edit]

goes from RSX BGA-pad AV18 (SPO0) to R2051 (22Ω) -> RS_SPDO // RS_SPDO goes to pin 2 of IC2501 (TC7WP3125FK)
RS_SPDO_33 comes from pin 7 of IC2501 (TC7WP3125FK)
RS_SPDO_33 goes to layerhole to R2412 and goes directly to IC2409 (TOSLINK connector)

SEM-001 / CECHGxx[edit]

goes from RSX BGA-pad AV16 (SPO0) to R2051 (22Ω) -> RS_SPDO0 // RS_SPDO goes to pin 2 of IC2501 (TC7WP3125FK)
RS_SPDO0_33 comes from pin 7 of IC2501 (TC7WP3125FK)
RS_SPDO0_33 goes to testpoint JL9202 and then directly to IC2409 (TOSLINK connector)
