LTC2323/LTC2321

Dual 16-Bit/14-Bit/12-Bit,

DESCRIPTION

Demonstration circuit 1996A features the LTC®2323 family. With up to 5Msps, these differential, dual channel, 16-bit, serial, high speed successive approximation register (SAR) ADCs are available in a 28-lead QFN package. The LTC2323 family has an internal 20ppm/°C reference and an SPI-compatible serial interface that supports CMOS and LVDS logic. Note the demo board is configured for CMOS operation by default; see the note under JP3 for LVDS operation. The following text refers to the LTC2323, but applies to all members of the family, the only differ ence being the sample rate and the number of bits. The

DC1996A demonstrates the DC and AC performance of the LTC2323 in conjunction with the DC890 PScope™ data collection board. Alternatively, by connecting the DC1996A into a customer application, the performance of the LTC2323 can be evaluated directly in that circuit.

QUICK START PROCEDURE

Demonstration circuit 1996A is easy to set up and evaluate for performance. Refer to Figure 1 and follow the proce dure below.

n

Connect the DC1996A to a DC890 USB high speed data collection board using edge connector P1.

n

Connect the DC890 to a host PC with a standard USB A/B cable.

n

Apply a low jitter signal source to J2 to test channel 2, or to J4 to test channel 1. Note that the DC1996A is capable of accepting a differential input signal as well as a single-ended signal. See the Hardware Setup section for the jumper positions that correspond to these configurations.

n

As a clock source, apply a low jitter 10dBm sine wave or square wave to connector J1. See Table 1 for maximum clock frequencies. Note that J1 has a 50Ω termination resistor to ground.

n

Run the PScope software (Pscope.exe version K73, or later) supplied with the DC890 or download it from

www.linear.com/software. Complete software doc-

umentation is available from the Help menu. Updates can be downloaded from the Tools menu. Check for updates periodically, as new features may be added.

The PScope software should recognize

-

and configure itself automatically.

n

Click the Collect button (Figure 2) to begin acquiring

the DC1996A

data. The Collect button then changes to Pause, which can be used to stop data acquisition.

HARDWARE SETUP

DEMO MANUAL DC1996A

SIGNAL CONNECTIONS

J1 CLK IN: This input has a 50Ω termination resistor,

and is intended to be driven by a low jitter 10dBm sine or square wave. To achieve the full AC performance of this part, the clock jitter should be kept under 2ps. This input is capacitively coupled so that the input clock can be either 0V to 3.3V or ±1.65V. This eliminates the need for level shifting. To run at the maximum conversion rate, apply the frequency specified in the Table 1.

J2 Ch2+ Input: In the single-ended configuration, this is the channel 2 signal input. For differential operation, this serves as the positive channel 2 signal input.

J3 Ch2– Input: This input is used only for differential operation. It serves as the negative channel 2 signal input.

J4 Ch1+ Input: In the single-ended configuration, this is the channel 1 signal input. For differential operation, this serves as the positive channel 1 signal input.

J5 Ch1– Input: This input is used only for differential operation. It serves as the negative channel 1 signal input.

J6 FPGA Program: Factory use only.

J7 JTAG: Factory use only.

JP1 +IN2 Coupling: Use this jumper to select AC- or DC-

coupling of the signal applied to J2. is DC. At very low input frequencies, using AC-coupling may degrade the distortion performance.

JP2 Mode: Use this jumper to select the signal input mode for the channel 2 input of the LTC2323. The default setting is Diff. The Diff setting accepts a single-ended signal from J2 and applies it as a differential signal to channel 2 of the LTC2323. The Bip setting accepts a single-ended signal from J2 and applies it as a single-ended bipolar signal to channel 2 of the LTC2323. The Uni setting also accepts a single-ended signal from J2, but applies it as a unipolar signal to channel 2 of the LTC2323.

The default setting

JP3 Data Out: Use this jumper to select the data output format from the LTC2323. The default setting is CMOS. The output data will not be valid if the jumper is moved to the LVDS position unless the following changes have been made:

Install 100Ω S0402 resistors at R26, 75, 76, 99

Reprogram the CPLD through J6 using the program ming file LTC2323.pof found at:

http://www.linear.com/demo/DC1996A

Move JP3 to the LVDS position.

JP4 –IN2 Coupling: Use this jumper to select AC- or DCcoupling of the signal applied to J3. The default setting is DC. At very low input frequencies, using AC-coupling may degrade the distortion performance.

JP5 +IN1 Coupling: Use this jumper to select AC- or DCcoupling of the signal applied to J4. The default setting is DC. At very low input frequencies, using AC-coupling may degrade the distortion performance.

JP6 CM1: Use this jumper to set the DC bias point for the signal applied to J4 when JP5 (+IN1 coupling) is in the

AC position. The default setting is ADC. The EXT setting allows the use of an externally applied common mode voltage applied at E1 (EXT_CM1).

JP7 CM2: Use this jumper to set the DC bias point for the signal applied to J2 when JP1 (+IN2 coupling) is in the AC position. The default setting is ADC. The EXT setting allows the use of an externally applied common mode voltage applied at E2 (EXT_CM2).

JP8 Mode: Use this jumper to select the signal input mode for the channel 1 input of the LTC2323. The default setting is Diff. The Diff setting accepts a single-ended signal from J4 and applies it as a differential LTC2323. The Bip setting accepts a single-ended signal from J4 and applies it as a single-ended bipolar signal to channel 1 of the LTC2323. The Uni setting also accepts a single-ended signal from J4, but applies it as a unipolar signal to channel 1 of the LTC2323.

JP9 –IN1 Coupling: Use this jumper to select AC- or DCcoupling of the signal applied to J5. The default setting is DC. At very low input frequencies, using AC-coupling may degrade the distortion performance.

JP10 VCCIO: Use this jumper to select the VCCIO sup ply voltage. The default setting is 2.5V. The 1.8V setting selects a 1.8V supply voltage.

JP11 VDD: Use this jumper to select the VDD supply voltage. The default setting is 5V. The 3.3V setting selects a

3.3V supply voltage.

JP12 EEPROM: Factory use only.

JP13 OSC: Use this jumper to enable the onboard encode clock source. The default setting

is OFF. The ON setting

energizes this source. Refer to the DC1996A schematic for additional passive elements required to use the onboard source.
