Texas Instruments LMX2346TMX/NOPB
- Part Number:
- LMX2346TMX/NOPB
- Manufacturer:
- Texas Instruments
- Ventron No:
- 2981076-LMX2346TMX/NOPB
- Description:
- IC FREQ SYNTH 2.0GHZ RF 16-TSSOP
- ECAD Model:
-
- Datasheet:
- LMX2346TMX/NOPB
Description
The LMX2346/7 are high-performance frequency synthesizers with an integrated 32/33 dual modulus prescaler. The LMX2346 is designed for RF operation up to 2.0 GHz, while the LMX2347 is designed for RF operation up to 2.5 GHz. Using a proprietary digital phase-locked loop technique, the LMX2346/7 generate very stable, low-noise control signals for UHF and VHF voltage-controlled oscillators. Serial data is transferred into the LMX2346/7 via a three-line MICROWIRE interface (DATA, LE, CLOCK). Supply voltage range is from 2.7V to 5.5V. The charge pump provides 4 mA output current. The LMX2346/7 are manufactured using National's 0.5μ ABIC V silicon BICMOS process and are available in 16-pin TSSOP and 16-pin CSP packages.
Features
RF operation up to 2.5 GHz
2.7V to 5.5V operation
Digital & Analog Lock Detect
32/33 Dual modulus prescaler
Excellent Phase Noise
Internal balanced, low leakage charge pump
Pin Compatible to LMX2323
Applications
Cellular DCS/PCS/3G infrastructure equipment
Wireless Local Area Networks (WLANS)
Other wireless communication systems
