The ADS58J89 is a high-linearity, quad-channel, 14-bit, 250/500-MSPS IF (intermediate
frequency) receiver. The four channels contain 500MSPS 14-bit ADCs followed by signal processing
for wireless infrastructure systems. The channels can be configured in various modes depending on
bandwidth, resolution and sample time requirements. The signal processing block contains selectable
modes for decimation filters, SNR Boost filters, resolution versus time and time-division duplex
(TDD) burst mode. Designed for high antenna count systems, the 4 channels provides high bandwidth
and linearity to multi-channel receivers in a small footprint. The device can be dual function as
traffic receiver and power amplifier linearization feedback path in TDD systems.
Key Specifications:
- Power Dissipation: 875 mW/ch
- Input Bandwidth (3dB): 900 MHz
- Aperture Jitter: 98 fs rms
- Channel Isolation: 85 dB
- Performance at ∫in = 170 MHz at 1.25 Vpp,
1 dBFS
- SNR: 65.8 dBFS
- SFDR: 85 dBc HD2,3 95 dBFS non HD2,3
