Description
Ground for TTL output : Normally 0 V. Parallel transmit data inputs to be serialized.
TX0 is serialized first and TX9 is last. Power supply for internal logic gates :
Normally 3.3 V. Ground for TX PLL : Normally 0 V.
Connect to external loop filter of TX PLL. Connect a capacitor (0.01 µF) between LPF_TX0 and LPF_TX1. Power supply for TX PLL : Normally 3.3 V. Loop back enable : When high, TX serializer output internally connects to RX deserializer input, SDOUT/SDOUT∗is held low/high, and SDIN/SDIN∗is disabled. When low, SDOUT/SDOUT∗and SDIN/SDIN∗are enabled. Power supply for internal logic gates : Normally 0 V. Reference clock for PLL and transmit byte clock (106.25 MHz). Supplied by the host system. Byte synchronization enable : When high, the positive comma character (0011111) detection circuit is enabled to establish byte synchronization (see Timing Chart). Test pin : Normally 3.3 V or open. Lock to reference clock : An active low input. LCKREF∗forces the PLL lock to the REFCLK supplied by the host system. Power supply for TTL output : Normally 3.3 V. Receive byte clocks recovered from the serial data (53.125 MHz). These clocks are 180 degrees out of phase, and RX0-9 are alternatively clocked on the rising edge of these clocks (see Timing Chart)
Parallel receive data output : RX0 is received first and RX9 is last.
Byte synchronization indicator : High when a positive comma character is detected (see Timing Chart) Connect to external loop filter of RX PLL. Connect a capacitor (0.01 µF) between LPF_RX0 and LPF_RX1. Power supply for RX PLL : Normally 3.3 V. Ground for RX PLL : Normally 0 V.
