3 Description

The ADC12DL500, ADC12DL1500 and

ADC12DL2500 are a family of analog-to-digital

converters (ADC) that can sample up to 500MSPS,

1.5GSPS, and 2.5GSPS in dual-channel mode and

up to 1GSPS, 3GSPS, and 5GSPS in single-channel

mode. Programmable tradeoffs in channel count

(dual-channel mode) and sample rate (single-channel

mode) allow development of flexible hardware that

meets the needs of both high-channel count or wide

instantaneous signal bandwidth applications.

The devices uses a low-latency, low-voltage

differential signaling (LVDS) interface for latency

sensitive applications or when the simplicity of LVDS

is preferred. The interface uses up to 48 data

pairs, four double data rate (DDR) clocks, and

four strobe signals arranged in four 12-bit data

buses. The interface supports signaling rates of up

to 1.6Gbps. Strobe signals simplify synchronization

across buses and between multiple devices. The

strobe is generated internally and can be reset at

a deterministic time by the SYSREF input. Multidevice

synchronization is further eased by innovative

synchronization features such as noiseless aperture

delay (TAD) adjustment and SYSREF windowing.
