Description

INPUT - TTL: Serial Loopback enable input. Normal operation when HIGH. When

LOW, Rx+/- is looped back to Tx+/- internally for diagnostic purposes. Refer to Table 2

and related description.

INPUT - TTL: Loopback Enable Pins. When LPNx is LOW, PLUP/SLPN impact

Channel x. When HIGH, PLUP/SLPN have no effect on Channel x.

INPUT - TTL: Enables SYNCx and word alignment when HIGH. When LOW, keeps

current word alignment and disables SYNCx (always LOW).

OUTPUT - TTL: Comma Detect for Channel x. This output goes HIGH for half of an

RCx1 period to indicate that Rx(0:9) contains a Comma Character (‘0011111XXX’).

SYNCx will go HIGH only during a cycle when RCX0 is rising. SYNCx is enabled when

ENCDET is HIGH.

ANALOG: Loop Filter capacitor for the Clock Multiply Unit. Typically 0.1 uF connected

between CAP0 and CAP1. Amplitude is less than 3.3V.

INPUT - TTL: JTAG Test Clock

INPUT - TTL: JTAG Test Mode Select

INPUT - TTL: JTAG Test Reset, Active Low

INPUT - TTL: JTAG Test Data Input

OUTPUT - TTL: JTAG Test Data Output
