What is MT3339?

This is a All-In-One GPS system on a chip (SOC). Suitable for a wide range of mobile, automotive, timing, personal tracker, flying drone, digital camera and industrial applications, MT3339 features high tracking sensitivity for enhanced performance in dense urban environments.

MT3339 requires just eight passive external components, and is pin-compatible with MediaTek MT3337 and MT3333 for a flexible way to develop multiple tiers of mobile device, while minimizing duplication in hardware development.

A high-performance single-chip GPS solution which includes on-chip CMOS RF, digital baseband, ARM7 CPU and an embedded flash (optional). It is able to achieve the industry’s highest level of sensitivity, accuracy and Time-to-First-Fix (TTFF) with the lowest power consumption in a small-footprint lead-free package. Its small footprint and minimal BOM requirement provide significant reductions in the design, manufacturing and testing resource required for portable applications.

Description

The DS90CR288MTD transmitter converts 28 bits of CMOS/TTL data into four LVDS (Low Voltage Differential Signaling) data streams. A phase locked transmit clock is transmitted in parallel with the data streams over a fifth LVDS link. Every cycle of the transmit clock 28 bits of input data are sampled and transmitted.

The DS90CR288 receiver converts the four LVDS data streams back into 28 bits of CMOS/TTL data. At a transmit clock frequency of 75 MHz, 28 bits of TTL data are transmitted at a rate of 525 Mbps per LVDS data channel. Using a 75 MHz clock, the data throughput is 2.10 Gbit/s (262.5 Mbytes/sec).

The DS90CR287 supports clock rates from 20 to 85 MHz. This chipset is an ideal means to solve EMI and cable size problems associated with wide, high-speed TTL interfaces.

Features

1. 20 to 75 MHz shift clock support
2. 50% duty cycle on receiver output clock
3. Best-in-Class Set & Hold Times on TxINPUTs and Rx OUTPUTs
4. Low power consumption
5. Tx + Rx Powerdown mode<400µW (max)
6. ±1V common-mode range (around +1.2V)
7. Narrow bus reduces cable size and cost
8. Up to 2.10 Gbps throughput
9. Up to 262.5 Mbytes/sec bandwidth
10. 345 mV (typ) swing LVDS devices for low EMI
11. PLL requires no external components
12. Rising edge data strobe
13. Compatible with TIA/EIA-644 LVDS standard
14. Low profile 56-lead TSSOP package
