16 LVPECL Output,

High-Performance Clock Buffer

Check for Samples: CDCLVP1216

FEATURES

DESCRIPTION

The CDCLVP1216 is a highly versatile, low additive

jitter buffer that can generate 16 copies of LVPECL

clock outputs from one of two selectable LVPECL,

•

2:16 Differential Buffer

Selectable Clock Inputs Through Control Pin

Universal Inputs Accept LVPECL, LVDS, and

LVCMOS/LVTTL

LVDS, or LVCMOS inputs for

variety of

communication applications. It has a maximum clock

frequency up to 2 GHz. The CDCLVP1216 features

an on-chip multiplexer (MUX) for selecting one of two

inputs that can be easily configured solely through a

control pin. The overall additive jitter performance is

less than 0.1 ps, RMS from 10 kHz to 20 MHz, and

overall output skew is as low as 30 ps, making the

device a perfect choice for use in demanding

applications.

16 LVPECL Outputs

Maximum Clock Frequency: 2 GHz

Maximum Core Current Consumption: 110 mA

Very Low Additive Jitter: <100 fs,rms in 10-kHz

to 20-MHz Offset Range

•

2.375 V to 3.6 V Device Power Supply

Maximum Propagation Delay: 550 ps

Maximum Output Skew: 30 ps

The CDCLVP1216 clock buffer distributes one of two

selectable clock inputs (IN0, IN1) to 16 pairs of

differential LVPECL clock outputs (OUT0, OUT15)

with minimum skew for clock distribution. The

CDCLVP1216 can accept two clock sources into an

input multiplexer. The inputs can be LVPECL, LVDS,

or LVCMOS/LVTTL.

LVPECL Reference Voltage, V_{AC_REF}, Available

for Capacitive-Coupled Inputs

•

Industrial Temperature Range: –40°C to +85°C

ESD Protection Exceeds 2 kV (HBM)

Available in 7-mm × 7-mm QFN-48 (RGZ)

Package

The CDCLVP1216 is specifically designed for driving

50-Ω transmission lines. When driving the inputs in

single-ended mode, the LVPECL bias voltage

(V_{AC_REF}) should be applied to the unused negative

input pin. However, for high-speed performance up to

2 GHz, differential mode is strongly recommended.

APPLICATIONS

•

Wireless Communications

Telecommunications/Networking

Medical Imaging

The CDCLVP1216 is packaged in a small 48-pin,

7-mm x 7-mm QFN package and is characterized for

operation from –40°C to +85°C.
