CLC005
ITU-T G.703 Cable Driver with Adjustable Outputs
General Description
National’s Comlinear CLC005 is a monolithic, high-speed
cable driver designed for the ITU-T G.703 serial digital data
transmission standard. The CLC005 drives 75
sion lines (Belden 8281 or equivalent) at data rates from DC
to over 622 Mbps. Output signal waveforms produced by the
CLC005 comply with G.703 specifications. Controlled output
rise and fall times (650 ps typical) minimize transition-
induced jitter. The output voltage swing, typically 2.0V, set by
an accurate, low-drift internal bandgap reference, delivers a
1.0V swing to back-matched and terminated 75 cable. Out-
put swing is adjustable from 0.7 V
nal resistors.
The CLC005’s class AB output stage consumes less power
than other designs, 185 mW with both outputs terminated,
and requires no external bias resistors. The differential in-
puts accept a wide range of digital signals from 200 mV
G.703 levels within the specified common-mode limits. All
this make the CLC005 an excellent general purpose high
speed driver for digital applications.
The CLC005 is powered from a single +5V or −5.2V supply
and comes in an 8-pin SOIC package.
