AD9627-11
GENERAL DESCRIPTION
The AD9627-11 is a dual, 11-bit, 105 MSPS/150 MSPS analog-to-
digital converter (ADC). The AD9627-11 is designed to support
communications applications where low cost, small size, and
versatility are desired.
The dual ADC core features a multistage, differential pipelined
architecture with integrated output error correction logic. Each
ADC features wide bandwidth differential sample-and-hold analog
input amplifiers supporting a variety of user-selectable input
ranges. An integrated voltage reference eases design considerations.
A duty cycle stabilizer is provided to compensate for variations
in the ADC clock duty cycle, allowing the converters to maintain
excellent performance.
The AD9627-11 has several functions that simplify the automatic
gain control (AGC) function in the system receiver. The fast detect
feature allows fast overrange detection by outputting four bits of
input level information with very short latency.
In addition, the programmable threshold detector allows moni-
toring of the incoming signal power using the four fast detect bits
of the ADC with very low latency. If the input signal level exceeds

the programmable threshold, the coarse upper threshold indicator
goes high. Because this threshold indicator has very low latency,
the user can quickly turn down the system gain to avoid an over-
range condition.
The second AGC-related function is the signal monitor. This block
allows the user to monitor the composite magnitude of the
incoming signal, which aids in setting the gain to optimize the
dynamic range of the overall system.
The ADC output data can be routed directly to the two external
11-bit output ports. These outputs can be set from 1.8 V to 3.3 V
CMOS or 1.8 V LVDS.
Flexible power-down options allow significant power savings,
when desired.
Programming for setup and control is accomplished using a 3-bit
SPI-compatible serial interface.
The AD9627-11 is available in a 64-lead LFCSP and is specified
over the industrial temperature range of −40°C to +85°C.
