Pin Connections
19
GNDX
GNDX
Reference oscillator ground.
20
BASE
BASE
Reference oscillator base. The
base is the reference oscillator
input. An on-chip capacitor trim
network is also included to
allow the user to use relatively
inexpensive crystals.
21
EMM
EMM
Reference oscillator emitter.
A bias current of 50
μ
A is
supplied internally to the
emitter.
22
COLL
COLL
Reference oscillator collector.
The collector is tied to VCC.
The pin of the IC is bypassed
to gnd.
23
DCVCO
DCVCO
Data Clock Loop Filter VCO
control voltage. This pin can be
used to raise/lower the loop
corner frequency in conjunction
with the DCCP pin and external
components.
24
DCCP
DCCP
Data Clock Loop Filter charge
pump.
25
VCCDC
VCCDC
Data clock VCC. The pin of the
IC is bypassed to gnd.
26
RTXEN
RTXEN
When RTXEN is asserted
(high), it controls the start of
the Rx or Tx cycle. Digital
input. The logic level is
internally shifted to the V
DD
supply.
