PRODUCT DESCRIPTION
The AD6645 is a high-speed, high-performance, monolithic
14-bit analog-to-digital converter. All necessary functions,
including track-and-hold (T/H) and reference, are included on
the chip to provide a complete conversion solution. The AD6645
provides CMOS-compatible digital outputs. It is the fourth
generation in a wideband ADC family, preceded by the
AD9042 (12-bit, 41 MSPS), the AD6640 (12-bit, 65 MSPS,
IF sampling), and the AD6644 (14-bit, 40 MSPS/65 MSPS).
Designed for multichannel, multimode receivers, the AD6645 is
part of Analog Device
’
s SoftCell
transceiver chipset. The
AD6645 maintains 100 dB multitone, spurious-free dynamic
range (SFDR) through the second Nyquist band. This break-
through performance eases the burden placed on multimode
digital receivers (software radios) that are typically limited by
the ADC. Noise performance is exceptional; typical signal-to-
noise ratio is 74.5 dB through the first Nyquist band.
The AD6645 is built on Analog Devices
’
high-speed complemen-
tary bipolar process (XFCB) and uses an innovative, multipass
circuit architecture. Units are available in a thermally enhanced 52-
lead PowerQuad 4
(LQFP_ED) specified from

PRODUCT HIGHLIGHTS
1. IF Sampling
The AD6645 maintains outstanding ac performance up to
input frequencies of 200 MHz. Suitable for multicarrier 3G
wideband cellular IF sampling receivers.
2. Pin Compatibility
The ADC has the same footprint and pin layout as the
AD6644, 14-Bit 40 MSPS/65 MSPS ADC.
3. SFDR Performance and Oversampling
Multitone SFDR performance of
–
100 dBc can reduce the
requirements of high-end RF components and allows the use
of receive signal processors such as the AD6620 or AD6624/
AD6624A.
