Product details
Overview
MAX2135AE/W+C76 from Maxim Integrated is a low-power, 6/7/8MHz ISDB-T and DVB-T diversity tuner IC for automotive TV reception. It performs broadband I/Q downconversion from 90MHz–862MHz to low-IF (93–105MHz or 173–227MHz), features integrated VHF/UHF tracking filters, monolithic VCO/tank, and operates from a single +2.7V to +3.47V supply with 396mW typical power consumption.
For engineers reviewing the MAX2135AE/W+C76 datasheet, MAX2135AE/W+C76 pinout, MAX2135AE/W+C76 application, or MAX2135AE/W+C76 equivalent, key selection considerations include its guaranteed -40°C to +85°C operation, 3.7dB UHF noise figure, -99dBm to +10dBm input dynamic range, I²C serial interface, and TQFN-56 (7mm × 7mm) package with exposed paddle.
Technical Context
The MAX2135AE/W+C76 implements a low-IF architecture with integrated LNAs, RF VGAs, and I/Q downconverting mixers across three frequency bands: VHF-L (90–108MHz), VHF-H (170–230MHz), and UHF (473–859MHz). Its on-chip crystal oscillator, frequency synthesizer, and output buffer/divider eliminate external PLL components.
It supports both ISDB-T (13-segment mode) and DVB-T standards with integrated 6MHz/7MHz/8MHz channel filters, and provides two low-power states: standby (serial interface active, signal path off) and full shutdown via external pin.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Pinout & Package
The MAX2135AE/W+C76 is housed in a 56-pin thin QFN package (7mm × 7mm) with exposed thermal paddle, optimized for automotive EMI and thermal performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC1, VCC2, VCC3 | Analog supply pins | Separate 2.7–3.47V supplies for LNA, mixer, and synthesizer blocks to minimize crosstalk |

Equivalent & Alternatives
The following parts are listed as comparable options for similar diversity tuner applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX2135B | Same pinout and package; revised VCO calibration algorithm improves phase noise by 2dB at 10kHz offset | Targeted at premium automotive systems requiring tighter EVM in dense urban multipath | Select MAX2135B when phase noise < -97dBc/Hz @ 10kHz is required; otherwise MAX2135AE/W+C76 remains optimal for cost-sensitive designs |
| Si2151-A10 | Single-ended IF output; no integrated crystal oscillator; requires external loop filter and SAW filters | Designed for lower-cost consumer TV dongles where board space and BOM cost are less constrained | Choose Si2151-A10 only if existing design uses external crystal and SAW filters - MAX2135AE/W+C76 offers higher integration and lower system-level component count |
Compared with MAX2135B and Si2151-A10, the MAX2135AE/W+C76 delivers superior integration (on-chip crystal, VCO, tracking filters), lower UHF noise figure (3.7dB), and automotive-grade temperature range (-40°C to +85°C), making it the preferred choice for space- and power-constrained in-vehicle TV systems.

FAQ
What is the operating temperature range specified for the MAX2135AE/W+C76?
The MAX2135AE/W+C76 is specified for operation from -40°C to +85°C. This extended temperature range is validated per AEC-Q100 stress test requirements and ensures reliable performance in automotive under-dash and dashboard environments where ambient temperatures fluctuate widely. The MAX2135AE/W+C76 maintains its 3.7dB UHF noise figure and -99dBm sensitivity across this full range.
Does the MAX2135AE/W+C76 support both ISDB-T and DVB-T standards simultaneously?
Yes, the MAX2135AE/W+C76 supports both ISDB-T (including 13-segment mode) and DVB-T (6MHz, 7MHz, and 8MHz channel bandwidths) within the same hardware configuration. Band selection and IF output frequency are configured via its I²C interface. The MAX2135AE/W+C76 does not require firmware changes or hardware modifications to switch between these standards.
What external components are required for basic operation of the MAX2135AE/W+C76?
The MAX2135AE/W+C76 requires only a 16–18MHz fundamental-mode crystal, decoupling capacitors on each VCC pin, and AC-coupling capacitors on the differential I/Q outputs. All VHF/UHF tracking filters, VCO tank, and channel filters are fully integrated - no external SAW filters, loop filters, or varactor diodes are needed. This minimizes bill-of-materials for the MAX2135AE/W+C76.
How does the standby mode of the MAX2135AE/W+C76 differ from full shutdown?
In standby mode, the MAX2135AE/W+C76 disables its RF signal path (LNAs, mixers, VGAs) while keeping the I²C interface and internal registers powered and accessible - enabling rapid channel rescan. Full shutdown, activated via the SHDN pin, powers down all circuitry including registers, requiring full reinitialization. Both modes are supported in the MAX2135AE/W+C76 for flexible power management.
Is the MAX2135AE/W+C76 pin-compatible with other members of the MAX2135 family?
Yes, the MAX2135AE/W+C76 is pin-compatible with the MAX2135A and MAX2135B variants, sharing identical 56-pin TQFN (7mm × 7mm) packaging and pin assignments. This allows drop-in replacement for qualification or performance upgrades. However, register map differences exist between revisions - firmware must be verified for compatibility when substituting the MAX2135AE/W+C76.
