4 pin Creative SB internal connector at the soundcard.
The internal I2S input connector is a 4-pin Molex header present on Creative Sound Blaster Live! cards (SB0060 and related, using the EMU10K1 chip) from the late 1990s. Creative describes it as the “Zoomed Video I2S digital input”, designed to accept a digital audio stream from an internal source via the standard I2S bus signals. Only one of the I2S input or Line In 2 may be active at any given time. The connector carries serial data, word-select/left-right clock, bit clock, and ground on four pins.
| Pin | Name |
|---|---|
| 1 | SDATA In |
| 2 | LRCLK In |
| 3 | GND |
| 4 | BCLK |
Signals
- SDATA In — serial I2S audio data input
- LRCLK In — left/right word-select clock input, indicating which stereo channel is being transmitted
- GND — ground reference
- BCLK — bit clock input, clocking individual data bits on the SDATA line
Notes
The connector is a 4-pin Molex header on the card’s PCB. Creative’s documentation designates it as the Zoomed Video I2S digital input and notes that the I2S input and Line In 2 / Mic In 2 share a single input path; activating one disables the other. The individual pin-signal assignments match standard I2S bus conventions but are not published in a pin-level table by Creative.
