Inverting and non-inverting high speed differential inputs of the deseralizer. On-chip
termination resistors connect from RI+ and RI to an internal reference. On-chip
termination resistors are configured for AC-coupled applications.

pull down
Transmit data word.
In 10-bit mode, the 10-bit code-group at DIN [0–9] is serialized with the internal 8b/
10b encoder disabled. Bit 9 is the msb.
The 8B/10B specification is defined in IEEE 802.3-2000 section 36.2.2
O, LVTTL or 1.8V
LVCMOS Internal
pull down
Deserialized receive data word.
In 10-bit mode, ROUT [0-9] is the deserialized received data word in 10-bit code group.
Bit 9 is the msb.
The 8B/10B specification is defined in IEEE 802.3-2000 section 36.2.2

pull down
I/O, LVTTL or 1.8V
LVCMOS
Inverting and non-inverting differential serializer reference clock. A low jitter clock
source should be connected to REFCLKP & REFCLKN.
Transmit clock. TXCLK must be synchronous to REFCLK to avoid FIFO under/
overflow though it may differ in phase.
52
RXCLK
Write mode: RXCLK is recovered clock output pin.
Read mode: RXCLK is an input pin. ROUT [9:0] are latched out on RXCLK rising and
falling edges. RXCLK must be synchronous to the incoming serial data to avoid FIFO
over/underflow, though it may differ in phase. See RXCLKMODE pin description for
more details.
30.72 MHz output clock. (OPMODE must be low.)

LOS
O, LVTTL or 1.8V
LVCMOS
Receiver CPRI loss of signal (LOS) status (8-bit mode only).
0 = signal detected (per CPRI standard)
1 = signal lost (per CPRI standard)
Receiver PLL lock status
0 = Receiver PLL locked
1 = Receiver PLL not locked
