Description
Max9324 One-to-five Lvpecl/lvcmos Output Clock And Data Driver
Manufacturer
Maxim Integrated Products, Inc.
Datasheet
The MAX9324 low-skew, low-jitter, clock and data driver
distributes a differential LVPECL input to four differential
LVPECL outputs and one single-ended LVCMOS output.
All outputs default to logic low when the differential inputs
equal GND or are left open. The MAX9324 operates from
3.0V to 3.6V, making it ideal for 3.3V systems, and con-
sumes only 25mA (max) of supply current.
The MAX9324 features low 150ps (max) part-to-part
skew, low 15ps output-to-output skew, and low 1.7ps
RMS jitter, making the device ideal for clock and data
distribution across a backplane or board. CLK_EN and
SEOUT_Z control the status of the various outputs.
Asserting CLK_EN low configures the differential (Q_,
Q_) outputs to a differential low condition and SEOUT to
a single-ended logic-low state. CLK_EN operation is
synchronous with the CLK_ inputs. A logic high on
SEOUT_Z places SEOUT in a high-impedance state.
SEOUT_Z is asynchronous with the CLK (CLK) inputs.
The MAX9324 is available in space-saving 20-pin
TSSOP and ultra-small 20-pin 4mm
packages and operates over the extended (-40°C to
+85°C) temperature range.
