AD6635 is a 4-channel, 80 MSPS WCDMA Receive Signal Processor (RSP) that integrates a proprietary ADC, filters, and analog baseband processors to provide a complete WCDMA receiver.
The AD6635 is a multimode, 8‑channel digital Receive Signal Processor (RSP) designed for WCDMA, GSM/EDGE, cdma2000 and other multicarrier wireless applications. It integrates four wideband inputs, programmable digital AGC loops, and flexible output ports for high‑speed data transfer to DSPs.
Key features include four 16‑bit parallel output ports, four 8‑bit link ports, four programmable AGC loops with 96 dB range, digital resampling, and a RAM‑based coefficient FIR filter with up to 160 taps. The device operates from 2.25 V to 2.75 V core supply and supports up to 80 MHz clock rates.
| Core supply voltage (VDD) | 2.25 V – 2.75 V |
|---|---|
| I/O supply voltage (VDDIO) | 3.0 V – 3.6 V |
| Ambient temperature range | -40 °C – +85 °C |
| Logic compatibility | 3.3 V CMOS |
| Power dissipation at 80 MHz | 2.8 W |
The AD6635 includes four programmable digital AGC loops with a 96 dB gain range.
It is supplied in a 324‑lead plastic ball grid array (PBGA) package.
