CY2PP3210
Dual 1:5 Differential Clock/Data Fanout Buffer
Features
Functional Description
The CY2PP3210 is a low-skew, low propagation delay dual
• Dual sets of five ECL/PECL differential outputs
• Two ECL/PECL differential inputs
• Hot-swappable/-insertable
• 50 ps output-to-output skew
• 150 ps device-to-device skew
1-to-5 differential fanout buffer targeted to meet the require-
ments of high-performance clock and data distribution applica-
tions. The device is implemented on SiGe technology and has
a fully differential internal architecture that is optimized to
achieve low signal skews at operating frequencies of up to 1.5
GHz.
The device features two differential input paths that are differ-
ential internally. The CY2PP3210 may function not only as a
differential clock buffer but also as a signal-level translator and
fanout distributing a single-ended signal. An external bias pin,
VBB, is provided for this purpose. In such an application, the
VBB pin should be connected to either one of the CLKA# or
CLKB# inputs and bypassed to ground via a 0.01-µF capacitor.
Traditionally, in ECL, it is used to provide the reference level
to a receiving single-ended input that might have a differential
bias point.
Since the CY2PP3210 introduces negligible jitter to the timing
budget, it is the ideal choice for distributing high frequency,
high precision clocks across back-planes and boards in
communication systems. Furthermore, advanced circuit
design schemes, such as internal temperature compensation,
ensure that the CY2PP3210 delivers consistent performance
over various platforms.
• 500 ps propagation delay (typical)
• 0.8 ps RMS period jitter (max.)
• 1.5 GHz Operation (2.2 GHz max. toggle frequency)
• PECL mode supply range: VCC = 2.5V± 5% to 3.3V±5%
with VEE = 0V
• ECL mode supply range: VE E = –2.5V± 5% to –3.3V±5%
with VCC = 0V
• Industrial temperature range: –40°C to 85°C
• 32-pin 1.4-mm TQFP package
• Temperature compensation like 100K ECL
• Pin compatible with MC100ES6210
