Operating Mode Transitions MODE TRANSITION USE CASE TRANSITION SPECIFICS Shutdown → Standby Drive RXEN high to enable 1. RXEN high > 10 µs receiver 2. Receiver enters standby mode a. R[0:7]=G[0:7]=B[0:7]=VS=HS remain high and DE=PCLK low b. Receiver activates clock input monitor Standby → Acquire Transmitter activity 1. CLK input monitor detects clock input activity detected 2. Outputs remain static 3. PLL circuit is enabled Acquire → Receive Link is ready to receive 1. PLL is active and approaches lock data 2. PLL achieves lock within twakeup 3. D1, D2, and/or D3 become active depending on LS0 and LS1 selection 4. First Data word was recovered 5. Parallel output bus turns on switching from static output pattern to output first valid data word Receive → Standby Transmitter requested to 1. Receiver disables outputs within tsleep enter Standby mode by 2. RX Input monitor detects VICM > 0.9 VDDLVDS within tsleep input common mode 3. R[0:7]=G[0:7]=B[0:7]=VS=HS transition to high and DE=PCLK to low on next voltage VICM > 0.9 VDDLVDS falling PLL clock edge (e.g. transmitter output clock stops or enters 4. PLL shuts down. Clock activity input monitor remains active high-impedance state) Receive/Standby → Turn off Receiver 1. RXEN pulled low for > tpwrdn Shutdown 2. R[0:7]=G[0:7]=B[0:7]=VS=HS remain static high or transition to static high and DE=PCLK remain or transition to static low 3. Most IC circuitry is shut down for least power consumption 11 Submit Documentation Feedback |
